I didn't want to steal someone else's blog but Rags comment:
I would suggest that you make sure to have your non-Skid weekends fully booked with meaningful activities for you and DH and do the same for your skid weekends sans DH and the Skid.
If the Skid's presence is nauseating to you... remove yourself from his presence.
Better yet... rather than letting SS evict you from your home..... send he and DH out and about dealing wit the errands. After all, since you and DH will be maximizing your non-skid time with enjoyable things that leaves only non-skid time for chores, errands, etc.... Load them up with Honey-do's on Skid days.
What better way for a 14yo young man and his dad to bond and spend meaningful time together than working? There is often nothing more enjoyable than a man and his son to work together, for dad to transfer knowledge to a young man. For sure that is the case when the young man in question is pleasant and of suitable character. When the kid is a toxic crotch nugget... that same activity is a living hell. Either way it will be valuable time for DH and his .... son.

A couple of times in the past I have bought them (SO and skids) a gift a gift card to the movies along with a gift card for a place to eat not because I am nice but because I wanted my house to myself for 3 hours bc it doesn't get old always being "away" when the skids are there?? I work hard during the week and need my down time at my home sometimes being "out" isn't what I want to do.

Do any of you have any other good ideas to share about how to get THEM to leave the house over "us" leaving the house? Please share because this could be a life changer for some of us that could be trapped in a bedroom somewhere.
