My DS and I wanted to see our half brothers over Easter so I sent a text to db2 to arrange details. The only day that he and db1(who's staying with them as he lives up north) can do is today. Fab. However, DS can't come as she's working. I feel bad but want to see my DBS as it's been a while since we last saw them. So AIBU to go to the zoo with them and our dcs?
