There's me thinking

There's me thinking is a idiomatic phrase that for some reason wasn't here on urban dictionary before, and for some equally unknown reason isn't present on any other online dictionary as well. But i'm here to bring this problem to an end.
This is something of a set phrase comes out of one's mouth whenever one thinks that someone was true but is proven wrong by something he just saw/heard/learned.

Exemples:
1:- Friend one, a bodybuilder wannabe, is caught having MacDonalds.
friend two: Whoa, wtf? And there's me thinking you were on a diet, huh?
2: -A non-binary leftist is caught eating meat.
Friend of him: lol, and there's me thinking all leftists were vegetarian.
3: If you see someone getting famous using an idea you thought you were the only one that had thought of, you can say: There's me thinking i was original. lol

Let it sit and think

When you let your vehicle sit after working on it and come back at a later time. This should give it enough time to fix itself or give you the tools to fix it.

Jeff: I was working on the risky ranger and it ran out of gas.
Joe: If you let it sit and think for a while it’ll run again soon enough.
