8yo SD told me to “shut up”
My SS (6yo) and SD (8yo) were called into the kitchen. SS was coming in quicker and yelled out "I'm going to win". SD responded "it's not a race". To which I jokingly responded "I guess it is now".
SD said (in a snotty tone) "shut up -my name-." To which my BF responded with a snicker. I turned to him and waited for him to respond appropriately and he didn't so I said "do you think that's funny?" He said no and then gave a weak reprimand and told her she should say she was sorry. There was little to no seriousness in his tone. I guess she mumbled a "sorry" which I did not hear.
I'm really upset by the fact that she thinks it would be acceptable to say that to me. We don't generally speak that way. I have NEVER said that to them. I'm more disappointed with BF's reaction. What would you do?
