OP, why are you so concerned about what others do and why do you find it so difficult to accept that some people have a different lifestyle from the one you enjoy?
Not everyone is sporty - it isn't a crime. I would agree that staying inside and watching tv throughout the entire weekend every weekend doesn't sound that stimulating for young children, but are you sure this is all they do every weekend
?
I also think it depends on how tiring you find your job and how long your weekdays are. We do a mixture of errands, swimming lessons, parties, dog-walking, outings, baking and playing at home at weekends. My dc enjoy being able to relax at home but like the occasional 'big' outing fairly regularly too. I get tetchy and irratated by trivIal issues if we spend too much time 'lazing', so we try and balance everyone's preferences.
Tbh, life can be hard when you work, have small dc and don't have limitless money to spend on a variety of leisure activities (as, indeed, it can in other circs
). People need to do whatever helps them relax and recharge on their days off.
