MIL drama

Al
We recently found out we're having a baby girl and my MIL asked us if we're to have a boy what the name would be. So I told her my top favorites and she says to me those are all terrible hopefully once you have a boy these names will change. 
Who says this? I mean I'm extra sensitive right now but seriously, who the hell does she think she is? Btw she named my husband and he hates his name. So obviously she doesn't know anything about choosing names. 
Sorry about the rant just needed to get it off my chest!
