Input: Text: i'm a property manager. today i was bringing a new group of people into a student house. there's one guy that's still living in the house, and he doesn't know any of the new people living in. i figured i would knock on his door, and let him know the new tenants were here so that he could introduce himself.

it's important to note that i did let him know the day before that people would be coming by. his room is situated in the house where he can hear conversations downstairs, and the new group was fairly loud. so there's no reason this guy didn't know people were in the house.

we were all downstairs talking for a couple minutes, when i told them to hold on a minute so the guy upstairs could come say hi. i knock on his door, and say "hey (tenants name), can i come in?" he answers yes, so i start opening the door, then i hear "wait, no!" his door's already halfway open at this point, and i see him barely concealing a raging erection underneath a pair of sweatpants. this guy's got a box of kleenex on his bed, a garbage can close by, and a bottle of aloe vera next to the kleenex. worse, he's got a handful of the fucking aloe vera. on his television there's some anime playing(i don't watch anime so i couldn't tell you what show). i quickly say "you know what i'll come back!" 

this guy. this fucking guy decides to turn the awkward up a couple notches by saying "nono its okay i was just about to come downstairs." so he stands up, his boner is still making a tent out of his sweatpants(amateur didn't tuck it under his waistband), and starts *rubbing the aloe vera on his arms*. he's trying to play this off like he's got dry skin! so i make some comment about the weather being really dry this week, to help him save face, and turn around. he follows me downstairs and starts introducing himself and shaking the new tenants hands. i was speechless.
