Input: Text: tifu by not realizing how reddit's secret santa works. i'm fairly new to reddit and this was my first secret santa. i signed up for secret santa and got matched with someone. i was thinking that person also had me and we were responsible for getting each other gifts. that's how i thought it worked. i checked out the person's profile and it was barely filled out so i had a hard time figuring out what to do. 

one day i got a message from my secret santa saying they just had their so send out the gift and i should be receiving it soon. i was still unaware that the person i was gifting was not the person sending me a gift. i automatically assumed that the person i was gifting was a female and proceeded to look for a gift from there. i found a cool gift that i thought my receiver would like and had it sent. 

i was messaged again from my secret santa and i was informed that the people we're gifting are not the people sending us gifts. upon further evaluation of my receiver's secret santa profile, i slowly realized based on their likes and dislikes and their updated wish list that this person was most likely not a female (about 90% sure this is a man).

i sent this person a gift that they'll most likely never use if they turn out to be a male. 

i'm still hoping this person is a female because then the gift would be perfect.

happy holidays.
