I was hoping if I give one example people would give their opinions on if this is just really annoying or a bit controlling.
Sat in the living room with the lights on. DP walks in and turns them off as it's 'daytime'. DS8 gets up and turns them back on. DP asks why he's done that and then goes and turns them off again. Repeat a couple more times.
Now my DS8 isn't DP's, and DP doesn't even live with me.
This sort of thing happens quite often. Do I just have an annoying DP?!
