I am an older nanny and a widow so my social life might look very different from yours, OP. I love going for a run on Saturday and Sunday morning - undisturbed and silent - especially now that the weather should be getting cooler. I love being with adults - anyone I don't have to check the back of their pants for poo-poos!!! Adult music, adult company - coffee in bed with just me and my newspaper... Dinners with good friends.
I clean, grocery shop, do a little cooking on weekends to make the weekdays easier.
Every Sunday night I am so ready to see my charges - it's really wonderful having a job where you miss your "boss" on a Sunday night!
