Typhoid Peony Last week, out

Typhoid Peony
Last week, out of the blue, I got a call from a college classmate. I hadn’t seen or talked to her since 1997, so I was very surprised and happy to hear from her. Turns out she also has gotten married, and has two children — one a little older than Hambet and another 6 months old.
I was supposed to head over to her place tomorrow for a play date and lunch. I told her I’d bring dessert, and I was just starting a cake this afternoon when she gave me a call and asked to postpone the lunch — her older child was sick.
So we’ll get together next week. But why is this happening? This winter, every darn time I’ve tried to set up a play date, the other kid(s) get sick! Over and over again!
*sigh* Oh well. The county nature center is having a puppet show tomorrow, so I’ll freeze the cake for later and we’ll go to the puppet show for our alternate outing for the day. But why does it seem like I’m spreading illness through the phone?
