Input: Text: i work as a cashier at a grocery store. today, mother's day, we are constantly being given single flowers in a vase to give to the mothers who come through our lines. i knew from the get-go that i had to be careful how i gave them away; i knew it'd be my luck to set someone off accidentally (maybe mother's day is hard for some people).

so i was giving two nice white flowers to a group that was leaving (grandmother, mother, and kids) and i'd accidentally grabbed three. i turned to the next woman in line and went ahead and offered her son (standing right in front of the register) the flower. "wanna give it to your mom for me, bud?" i asked, motioning to the woman.

he grabs it, laughing. i look at her... her face had dropped. angry, very angry. quite unhappy. "that's my brother."

the rest of the transaction went in absolute silence.

TIFU by giving out flowers.
