Attended the twins’ open house.
If you allow your first grader to run around pointing at my kids and screaming, “They adopted you. They adopted you,” then I’m going to tell him, “No. We used a surrogate and an egg donor.” When he then says, “What are those?” I’m going to tell him, “Ask your mommy and daddy.”
You can now explain all the biology to your rude ass kid since you haven’t taught him any damn respect for adopted children.
