I'll help as much as I can

How dumb is the above statement? Still, I told this to someone the other day and immediately felt so wrong..stupid.

In my defense, the reason why I got carried away was because the other person asked me for information about something they (wrongly) think I am good at, and they sounded reasonably not-manipulative. (Naive..I know.) So this desire to show off my meager knowledge gave me a black out.
Secondly, I haven't really been of much help to the society lately so was kinda out of touch on how to behave.
