I use to babysit a deaf kid. It’s where I learnt sign at around 13. Anyway - never again… those dearies NEVER listen 
- couldn’t get him to hear a word I was saying!
Hahahahaha …never pissed the kid off though. He was 7 and I knew about the “deaf rage super-strength”
All kidding aside, when I was younger I somehow got myself involved within the deaf community. We had lived in a larger city at the time. Must have been the babysitting skills.
IF you have never raised or been around kids - none of them have any listening skills regardless of “hearing”.
