For the record.

I am never going to say anything detrimental to my supposed children.

The words "useless" and "annoying" will never coincide with them. Other people may say those things, but it is never a parent's place to verbally humiliate their child. I think that some people just say what pops into their heads and don't think about the consequences. I myself may be included in that category at some times, but some people seem to come to it regularly.
