sumtimes if i was upset if i told him sumthin and wed end up arguin coz he cud sumtimes cum across as cold and i told him he was an emotiuonless robot 4 just standin ther when i cried
i did very much regret this and apologzed 2 him this was b4 i read up on his aspergers
iv had a few mental health probs in past but ok at mo
