Happy Monday, lovely people of the thread.
We had a nice Zoom call last night with DD and my MIL. DD has moved from the dorm she was in over the summer, which had air conditioning, to her dorm for the new academic year, which does not have air con. Fortunately, the weather will be cooler this week.
I had a crown come off a tooth last night during dinner. I've been able to book a appointment this afternoon at 3:00 to have it cemented back on, which is usually so quick that they don't normally charge me to do it.
Helena, I am in awe of your ability to manage four children. 
Math, we having hummingbirds who come to visit the flowers on my deck. It drives dboycat batty, as they are much too fast for him to catch.
