My exercise regime includes an aquafit class early on Sunday mornings. It is always crowded and regulars try, sometimes with great vigour, to get to their favourite spots at the front of the pool as soon as they can. This morning we were joined by a woman in her last trimester of pregnancy. I think this was her first time in this class. She was relegated to a spot in the back corner of the pool near where I was working out. The aquafit instructor noticed this newcoming after leading the class for about 10 minutes. She walked over to her and quietly added some special instructions so that no harm would come from exercise that may be too strenuous, and then the instructor casually walked back to the front of the pool shouting instructions to the rest of us all the way.
It's challenging to notice someone special in a crowd who may need some individual attention. I was impressed.
