My parents have three daughter (and a son.) All three of us girls married. Enter the three son-in-laws. They have an unwritten code. Only one can attend any given family event. Well, it was never really established this way or thought out but it has now become the family joke. If my husband is there, the other two are inevitably not. If my sister's husband is there, the other two are not. No one ever plans it this way but between work schedules and traveling it never quite works out for them to be at the same family event. One would think they plan it out and take a rotation of who's turn it is to show up.
Last night we had a great cook out at my parents house. It was my husband's turn to show up.
Maybe this year at family camp they will all be in the same place at the same time. If it happens I will be sure to get a picture.
