You got into Patna Junction at six in the morning. Auto home. Slept till noon.
The bag is still standing in the corner of the room. Zipped. Exactly where you dropped it.
That was Sunday. It is Wednesday.
Inside it is everything you wore for four days. The kurta from the second night. Three pairs of socks. The towel from your cousin's bathroom that never really dried. All of it pressed flat against itself, in the dark, at thirty-one degrees, in September air that is already holding as much water as it can.
A closed bag is a warm wet box
Mould and bacteria need three things. Water, warmth, food.
Your sweat is the food. Salt, skin oil, dead skin, a little of Saturday's dal on the cuff. The towel is the water. Patna supplies the warmth for nothing.
Zip that bag and you have built them a perfect room. No air moving. No light. Nothing drying.
Forty-eight hours is enough. That sour, flat, slightly sweet smell when you finally open the zip has a name. Mildew. It is alive, it has been eating your kurta since Sunday, and it is not going to leave because you hung the kurta out on the balcony for an hour.
The clothes you never even wore
Here is the part that catches people.
Two shirts at the bottom. Folded, clean, packed with good intentions, never taken out. They come out of the bag smelling exactly like the shirts you did wear.
Smell is not a feeling. It is actual molecules in the air, and cotton pulls them in and holds them the way a sponge holds water. Four days sealed next to a damp towel and a clean shirt has absorbed the whole thing.
You will not notice it. It is faint. So the shirt goes back into the almirah, and now the almirah has it too. Give it a fortnight and everything on that shelf smells slightly of a bag.
One trip can take down a whole wardrobe.
Nobody has ever washed the bag
Those wheels rolled down platform one. Through the standing water at the bottom of the foot overbridge ramp. Across the floor of a shared auto at Mithapur. Over the lane outside your gate where the water sits for two days after every rain.
Then you put the bag on your bed to unpack.
The inside is fabric too. That lining has been holding damp clothes since you bought the bag, and it has never once been cleaned. It is the reason a bag smells before you put anything in it.
The ten minutes when you get home
Do this the day you arrive. Not tomorrow.
Unzip the bag and empty it completely onto the floor. Not onto the bed.
Anything damp goes straight onto a hanger under the fan tonight. Damp is not a category of clothing. It is a deadline.
Worn clothes go into the wash pile. Not into the almirah "just for now". That "just for now" is exactly how an almirah starts to smell.
The clean shirts you never wore go into the wash pile as well. I know. Wash them anyway. It is one shirt today or a whole shelf next month.
Then stand the bag open on its end, mouth down, under the fan for a full day. If there is sun on the terrace, give the open lining an hour of it. Direct sun does more to that lining than anything you can spray into it.
Packing the other way
The same rules going out.
Never pack anything that is even a little damp. Not the towel. Not the jeans that felt almost dry on the line at seven in the morning. Inside a closed bag, almost dry is wet.
Carry a separate cloth bag for worn clothes. Cotton, not polythene. A polythene bag is a sealed jar with sweat in it, and by day three it will have gone properly bad. Cotton lets water out.
Roll your clothes instead of stacking them flat. Rolls leave gaps, gaps hold air, air keeps things dry. It also means fewer creases when you get there.
The season is about to start
From now until Chhath, half of Patna is on a train. People coming home from Delhi and Bengaluru and Pune. People going back after the last arghya. Bags packed in a hurry, opened in a hurry, packed again.
The bags that come back from that trip are the worst ones of the year. Four days of festival clothes, heat, crowd, and a wet towel, and then the bag sits in the corner while everyone recovers.
If you would rather not spend that first evening at the tap, put the whole pile into one bag and leave it outside your door. We pick it up from your gate, wash each thing the way it needs washing, and bring it back folded. You unpack once and it is finished.
Either way, open the bag tonight.
It was made to carry your clothes across the country. It was never made to keep them.
