Replying to My brother is retarded

so im 19, home on christmas break until monday, and my younger brother is 16. so he always has friends over and they drink in the basement after my parents go up to bed around 10:30 or so.
so last night, his friends came over around 10ish with 2 40's, and 2 cases of beer. my brother, thinking that both parents are upstairs in their room, tells them quietly to go down into the basement and take their beer with them. he walks off but he soon hears a scream followed by a bunch of running up stairs.
turns out my mom was downstairs doing laundry and came to the bottom of the stairs just as my brothers friends were going downstairs. my mom fakes a scream, (she thought it was funny) and then starts laughing. all the kids run out scared, leaving the beer at our house.
my mom didnt care that much, but my dad shit a brick. so now my brother is grounded for a while and my parents gave me all the beer as a going away present back to college.

haha, i love it
