We're home, but I think it is spring

It is Monday morning and...my son is not at school. After talking to various people who basically said, "How long are you prepare to keep him home for - 4 weeks?" We were ready to send him on his merry way. Then he got up this morning and wasn't keen to go. We are all a bit sniffly, which I am 99% certain is due to spring time allergies. The birds are frisky, the flowers are blooming, the grass is growing faster and ach-hoo. But with everything going on, figured it wouldn't hurt to keep him home
