Input: Text: this fuck up actually happened a few weeks ago when the mcdonalds monopoly was going on but i only just thought to post.

anyway, i was walking through town and happened to walk past a homeless lady, i like to be generous where i can, but being a student i can't afford much and i give what i can so food/water etc.. if i have crisps in my bag i'll give them away, i rarely have change on me as i pay for everything on card so its usually items such as food or saniatry products. as i saw her i remembered that i had a voucher in my purse for a free apple pie and decided that she needed it more than myself. i presented the lady with the voucher only to be called a 'fucking tight bastard' and have her burst into tears on me. at this point people walking past are staring at me and shaking their heads at me as though i had just gone and kicked the woman. i was only trying to be kind, i now wish that i had just kept it.

TIFU by giving a homeless lady an apple pie.
