If you babysit or nanny, it can happen that people think the kids are yours. Here's a different take on it:

I am 1 1/2 years older than Hubs, but there are times when he looks like he could still be in high school (guy's 25 next month, I'm 26). I was at a doctor's appt, not pregnancy related, and somebody asked me if I needed a doctor's note for him to give to his school. I can only assume they thought I was his mom? That's just creepy and weird.
