There are a number of different things I tend to do on my days off from work. Most of the time it does not involve a day spent on the couch watching TV (that is typically reserved for sick days when I actually incapable of doing anything other than flipping channels on the remote).
Sometimes I have appointments scheduled for myself and the kids, sometimes its grocery shopping or chores around the house. On occasion, I do actually plan to at least go out for lunch with my hubby since we do after all have free childcare given the kids are in school on my day off usually.
Last year I signed up for the Parent Advisory Committee at my daughter's school. This was something I never did at my son's school in his elementary years for various reasons. The main reason being I just never truly felt I had a lot in common with most of the other parents in the school. My daughter's elementary school though is a different story, there is a real sense of community there and the whole school itself just has a whole different atmosphere.
