Input: Text: recently, my so and i have been getting a lot more serious, and the topic of sex has been brought up more than a few times. because of this, i figured i could be proactive and buy some condoms to be prepared for when the time came. 

i took a trip to my local target, grabbed the first box i saw and went to the checkout line. that right there is where i fucked up. not two minutes later, my girlfriend's grandmother walks into the same checkout line that i'm in, and notices me. she gives me a warm grandmotherly smile, and asks "whatcha gettin', acidwater?" she looks down, looks back up at me .. and i kid you not. i could literally watch that smile fade into oblivion. she took her cart, pushed it into the next lane, i paid, and left. no other words were exchanged.

i guess my efforts to prove that i'm not such a bad guy has been for nothing. 


it's been over 10 hours and i'm still in disbelief of the situation.

TIFU by practicing safe sex.
