Input: Text: tifu you guys. alright, so this happened about 8-9 years ago but still. i was a young 17 year old. at the time, i never had a girlfriend. in fact, the only time i had even kissed a girl was when i played truth or dare back in 6th grade. basically, i was naive and insecure. i didn't know what i was doing. 

so anyway, i was talking to this girl in one of my classes who i thought was very cute. we would talk every now and then so i asked her if she wanted to hang out sometime. looking back on it now, it was clear that she assume i was asking her out on a date. however, i was so naive that i literally thought it was just 2 people hanging out. either way, she said yes.

so i picked up and we went to macaroni grill. we had a great time, talking and laughing. if i had any clue at all, i would have said "this date is going great." nope. no clue at all. in fact, i still had no clue when she invited me inside after getting back to her house. she invited me in watch tv (the old-school version of netflix & chill). i was thinking, hell i was probably going to go home and watch tv anyway so why not.

when we first get it, she went upstairs while i hung out downstairs waiting for her to change and come back. i am looking around at all the pictures and such like i enjoy to do at new houses. i notice that her sister was this other girl that i had noticed at school. never spoke to her or anything but deff noticed her because, well, she was hot.

here is where the fuck up happens. my date comes down and the first thing i say was "why didn't you tell me your sister was so hot?" i just blurted it out. no. i didn't think it through or anything. i was looking at the picture when i noticed her coming down so that didn't help but still. i should have known better. anyway, after blurting that out, i realize what she was wearing. she had changed into one of those super short cotton shorts where you can almost see her ass and a cute little tank top. she was definitely planning on something happening. that is, until i fucked it up. for the rest of the night, she sat at one end of the couch with a couple throw pillows in between us. after watching tv for a while, i left still completely oblivious to the fuck up that just occurred. 

tifu; hang out with girl, girl invites me in, tell her that her sister is hot, go home a virgin.
