Both my sisters have text me over the last couple of days asking what we are doing for Mother's day. I have told them both the same thing, that I wasn't planning on seeing my mum this weekend as DS has something on 1-3pm (not sure if he is going yet though) and I am at theirs next weekend so will post her a card and give her a present next weekend. They live just over an hour away so it's not like I can just pop round like they can, (younger sister lives at home and older 20 mins away). I try to avoid going down consecutive weekends as it always gets a bit expensive. My older sister didn't text back when I said I wouldn't be there and my younger just said they will take her out and we can do something next weekend too. I feel guilty now but I don't think I have doe anything wrong. I also think they forget that I am a mother myself and would like some time with my son on mother's day (they have no children). aibu?
