I had to giggle a little at this letter, because until my husband and I were officially married, his family considered me just some other person who just happened to be at all family gatherings. Through three years of dating, I was the photographer of many of these "family" portraits at Christmas, at the yearly family camping trip, and at other special occasions. I was simply the most convenient person to take a picture of the "family". I was not permitted to address his grandparents using the familial terms, MawMaw or PawPaw and was instead instructed to address them by their first names. I was reminded several times that, were we to marry, my status would change from a sort of "Welcome, But Definitely Outsider". And, it did!
But other things changed too. My mother-in-law now has a great scrapbook collection of events that she can pore over knowing that her daughter's husband is no longer in the family, while the "photographer" has been married to her son for 5 years. I keep wondering if she'll cut out his face and paste in mine?
While I harbor no real resentment over these things, I find it strange and amusing that people continue to draw these lines and barriers to distinguish who is considered "family" and do not take into consideration that the Significant Other might be more committed to their offspring than they think. Just by the fact they are at all attending the seemingly endless (sometimes painful) Christmases, camp outs and birthdays, (sometimes at the expense of time with their own family) should say something.
I say the kid stays in the picture.
