Busy Little Social Calendars

In the course of two days this weekend my three children will attend 4 parties between them.  Yes, I understand that when you have teens your parental role is a kind of cross between a taxi and an ATM,  but two of them are not teens yet (and won't be for years)!  The teen's party was actually free and he found a ride.  I have no social engagements, but my 6 yo has two in one day.   It boggles the mind.
