you tend to realise several things.

1.  Infatuation and love affairs with phones.

2. Everything and everyone is a variable.
The probability of being on this lonely carriage again as that stranger with 5'o clock stubble sitting across you is infinitesimal.

So, when you find a constant, that is when things get interesting.

Uninterrupted eye contact.
The same dated train tickets stuffed deep into pockets.

3. All these people. All these faces.
I think I am getting to know love.
