So today I had it with ss15s moaning and complainig about everything. I decided to spend the day at the beach without neither as nor DH. I haven't been this relaxed in months! I did feel sort of bad for DH because he had to stay home with ss(I do not know why;maybe he felt obligated). As I sat in my beach chair, I came to an epiphany...SS has been acting out for the past 3 summers,right before he has to go home to his mom. Either he really enjoys the freedom here with DH and I OR he creates drama at the end of the summer so that he can tell his mom how an awful time he had....idk
