My son wants to come with us on mother-daughter day out, but I am going to refuse.
Is there a reason behind that?
No I just want to spend time with my daughter alone.
It is good to have a mommy daughter day away from the boys. You should also make sure you take your son out alone.
My son is not a little bitch. He is a future supervillain, I want him to be ready to go evil....
It sounds like you're being really harsh on your son, and that could mess him up in the future. Maybe promise him a mother-son day a few days or weeks from now so that he also has some time to look forward to with you?
