Just for all those specifically male orientated things that happen over the christmas period.
Like:
Doing the washing up after the christmas meal. Thank goodness that's done for another year!
Having to avoid sniggering when talking about legs and breasts when carving the turkey.
Having to put toys together.
Pretending to really like socks.
Putting up with children interfering when you're playing with their Lego for them.
