So the 35 year old son and I get into an argument yesterday.

You are almost 60, so between you and me you should be the more responsible one, he argues.

Which according to me is convenient.

. you think I've no brains, which is why you are disregarding my judgement, and we are having this argument in the first place..

So why do you expect maturity from a dumb person? Huh

Now just answer that!
