Links to my favorite guesses:
Congratulations to my daughter for swimming well at last Friday's swim meet! It was a treat to be allowed to come to one of your meets and watch you swim. You had banned me because I cheered too loud for you? That's silly! This time I kept my mouth shut and urged your father to cheer instead. So can I come to the next one? I will only yell a little bit. Maybe.
On a higher note, my family enjoyed a wonderful Christmas party with fellow pilots at our local airport. Santa arrived in an airplane, giving all the little kids a fun treat. Who is behind that beard? Why, it's my favorite flight instructor!
