Reducing people to tears is Not On, regardless of how much of a reason they do or don't have for bursting into tears (just having to live through being a fucking teenager is good enough, most days).

Yes, assuming that the tears are real and not performative.

I went to primary school with a girl named Michelle whose favourite trick was bursting into floods of tears and running to a teacher with a made up story about another students imaginary wrong doing.

So many times I got in trouble because I wasn't crying, and Michelle was sobbing and red in the face, so clearly *I* must be in the wrong. Spoiler: Michelle was a bully who liked getting other kids in trouble for no reason at all.

I wonder if Michelle went into acting...

But LW's daughter definitely seems to be in the wrong here, and I feel very sorry for the teammate who is having to deal with LW's daughter.
