I was due to meet with 2 colleagues this morning, one male who I will call M and the other female who I will call F. M didn't show up - it was unlike him and we were surprised but F and I met anyway
Later in the day, F ran into M and she asked him where he had been that morning. He was suitably mortified, apologised and said that the meeting must not have been in his calendar. F told me this later in the afternoon and said that she wasn't annoyed at him because a) it wasn't like him to forget and b) 'hes a man ' 
When I asked her what the fuck that had to do with anything (not in so many words!), she said that his wife probably organises his life for him outside of work and his PA probably does the same at work so he doesn't really know how to organise himself. I know that the concept of 'wifework' is well known and discussed on here, and that it often extends into the workplace. So is my colleague F just being realistic about how men's lives are often organised differently to women's lives, or is she being ridiculous and blaming the women in M's life for not organising him properly? Thoughts welcome
