Me and my roommate lived together for 2.5 years, and were best friends for about 5. I moved out for 6 months while subletting for an internship, and asked him to take care of my bike while im gone. I moved it to a safe place in the basement so no one takes it. When his friend visited him, he took out my bike so they can go somewhere with them, and he left mine locked outside our house. Now, after he left, our dorm did this thing they do to get rid of unused bikes, where they put some tape on it that says:”Remove this if this bike is in use” And they dispose of the bikes that still have the tape after a week or two. Of course, he didnt remove the tape from my bike, nor moved it to the basement which they dont check, and the bikes is now gone. I am pissed at him because in my mind its lowkey his fault its gone. Am I the asshole for being pissed at him?
