Not a valid one, it's a dismissal/ploy used to not state reason
When there is good reason you did not do your homework you have a valid excuse.
No, you cannot trespass someone without a valid reason.
no because kids need cars And why is that? Give me a valid reason.
wow that sounds messed up! Perhaps you should ask him why because there could be a valid reason, but if there isn't a valid reason I'd have a talk about that with him because I'm sure he's trying to protect you and all but that's no way to behave.

If you have a valid reason, certainly.
