AITAH for answering a genuinely stupid question/sentence with sarcasm?

Example 1:

I asked my partner to open the canned goods using the can opener (the manual one where you twist clockwise).

He said he 'don't know'.

I answered back, "I see. Then maybe you can try with your teeth".

Example 2:

My sister asked how to do freelancing two weeks ago (I'm a freelance Virtual Assistant btw).

I sent all the resources how to and she said Ok. A wk later, I checked the drive and she didn't even open one link.

She approached me again and said "I hope I can work as a freelancer too" to which I answered "Yes, you will be one. I can see the drive in you".

AITAH for getting satisfaction from my snarky remarks and my private joke towards their stupid questions?
