Input: Text: i wouldn't really say it's much of a fuck up since i never see people do this but i still consider it to be a normal. least that's what my parents taught me. first post on reddit btw.

i was going home on the 6 train in nyc headed towrds pelham bay and i get on the train and find a nice seat. a few stops later i notice a bunch of somewhat old people getting on the train. they weren't handicapped nor had a cain or any disabilities from what i first noticed. 

a lady, i'd say around 60 years old entered the train with a pully bag (idk the proper name), she looked around and just stood near the door. i didn't think anything of it. i finished eating my lunch (a samosa chaat, if you were curious) and just closed my eyes listening to lindsey stirling. 

a few stops later i looked to see what stop the train was on and the same lady was standing in the same spot. the lady was looking around the train and her eyes were red and she looked like she was crying a little. she was shaking a little but i didn't think much of it.

after a few stops, the train was much more crowded now with little room. the train stopped on 110th. someone got off and the lady was on her way there but some asshole rushed passed her and sat down. she looked hurt and disappointed. i began thinking what should i do. i mean i knew i should have immediately offered my seat but i didn't. i didn't know why either. the lady now was tearing up. 

the train cleared up a little and i finally noticed her knees shaking a little. i then immediately got up and gave her my seat and she said thank you. i feel like i should have noticed it much earlier. normally i'm much more observant but waking up at 5:30 in the morning to get to an 8am class is tiring but it's no excuse for my fuck up. i got off the train at parkchester which is like maybe a 40 minute ride from where the lady originally got on and she was still on the train. i guess she was headed further uptown. but regardless, i don't know if this qualifies for a tifu but it just left me with a nasty feeling knowing i could have offered myself earlier. just felt like a fuck up to me.

TIFU by not giving my seat up earlier
