Ok I do work part time. Average 35 hours a month. As a result I do virtually all the childcare, housework, laundry, ferrying kids around, medical and dental appointments etc etc for our 3 dds. Fair enough as youngest dds are now at school full time.
However it is annoying that I am also expected to be the one to send the thank you etc for dh's family. If my family send something I always reply but expect dh to deal with his family. He doesn't and I than get in-laws ringing me to find out if we received it! The undercurrent is of that it is my job to do it.
