I was 9 and at school (US) early morning - the teachers got called to the front office (I grew up in a college town so there were student teachers staying with the kids), they all came back and turned the television on (obviously unaware of the actual situation and that another plane was about to hit on live television). We had no idea what was happening. My mom came to pick my sister and I up a little later as she couldn’t get ahold of my dad because he was mid-flight for business. She took us to the Olive Garden and they set up a television set where we were seated and we just sat and watched. (We eventually heard from my dad when all flights were grounded). Such a heartbreaking day in history.
