I found it highly amusing when my brother was here with his fiance, and she kept referring to families with "only 6 kids" or something. It was kinda refreshing in a way.
Are all your siblings married? Ben is the first for us...which is why getting used to the idea is a little tough for me, especially being the oldest. ;-)
No, just the older two. But they have been married a while now... I forget. I am #3 and both of them were married for years by the time they were my age.
