Get in the shot!
Jenn, One time we rented a beach cottage, and told the owner I love the photos of your family, but why don't I see any of you there. She said she hates to have her picture taken. I told her I used to be like that, but then one day thought "I'll Never look this good again!" So why not? It's kind of sad to see photos with no middle aged women in them!
Now I have to say I look alot better now then I did last year at this time, but I'd like to encourage you to get in those snaps once in a while! You only go around once you know!
