person A: I got an ice cream cake for my birthday and it was really good. It was rather big so we had plenty left over we kept in the freezer. My husband took it out to defrost it enough to cut it while I wasn't home and totally forgot about it and it all melted. I was upset.
person B: I'm sorry to hear that! It sounds like an honest mistake. 
person A: I feel that its more like inconsiderate. My parents got me the cake and he forgot about it because he was losing in his video game. Honest mistake? Okay but seriously inconsiderate
person B: Oh wow_comma_ defenitly sounds like he was too focused on video games. Maybe talk to him about how it made you feel so you don't get resentful.
