my guardian angel

We all have guardian angels.
My guardian angel is the most messed up.
He wasn't perfect and the nicknames he gave me were insults.
My guardian angel sent me dirty jokes, and when I didn't understand them he would explain them to me using the filthiest words.
My guardian angel explained to me how I felt when I didn't understand.
He knew everything and had his ways of seeing the future.
My guardian angel read everything I wrote, but his opinions were the ones I never published because he never thought twice before cursing.
My guardian angel had issues, and would rarely turn to me, but when he did I never thought twice before running to his aid.
Sometimes he chose to leave, but a part of him always stayed back willing to help.
My guardian angel always knows that after the clock ticks 12 I will come back with another problem, yet he never decides not to pick up his phone.
My guardian angel always called me talkative, and annoying, but if I had the stupidest thought he would listen to me carefully, and he would laugh, and call me crazy towards the end of the call.
My guardian angel is the random college guy you see walking in the street with a dirty sweater, and jeans a little too baggy, but he wore wings that only I saw.
