Input: Text: there was this picture on imgur of two fat ladies in electric carts blocking a father's view but his son was truly handicapped and he mentioned that being fat is not a disability.  i agreed in it's context.  however, i was taking the bus in san francisco to the marina yesterday to enjoy the leisurely sun and water when my friend, timothy lee, were sneaking drinks on the bus in our secret pepsi cups and the bus comes to a halt.  the electric rail clicks downward and i hear this grumpy mean fat lady in an electric wheel chair which i assumed was because she was fat.  me and my big mouth, all eyes on her and i say to her...as impolitely as i could because i can be that way out of the blue, i said "mam, are you really handicapped or are you just fat?  bc fat isn't really a handicap, stupid drunken stupor, just joking on the square....and she says to me "i fucking got hit by a drunk driver on mission and 24th street and i am lucky to be alive"
the entire bus went quiet...i apologized and said we have been drinking...but it was too late...the humiliation was pouring from all the scowled faces inside the bus....i conceded and apologized and she told me to shut the fuck up and i rightly deserved it and took a tear in my asshole as i deserved the rage, and anger and nothing i said made it better...and the heat of the bus and the anger on people's faces...rightfuly so...so i got berated and i deserved it....boom...our stop, the marina and i bowed down apologized profusely...i was waiting for her to hit me with an iron from her purse...thankfully it didn't happen and now you know the rest of the story....
