Is it normal to ask strangers if a habit is normal?

It can be easier to ask strangers because they aren't biased by whatever else they know about you.

Only on IIN.

Sometimes people can be a little too hypercritical on IIN but it can work in OP's favor with most of the questions asked here. If you asked someone who knew you better they could see more of the whole instead of a little snippet, in effect giving you better advice. There are faults in both. Possible bias in one not enough information to go off of in the other. I think they're both valuable.

Well, that's the point of this very website.

Newbi, this must be your first visit to IIN.

That's why IIN is here.
