Need Suggestions: Still feel older and "different" than other families

I was 38 (hubby was 34) when my daughters were born and, yes, there are times I feel much older than all the other moms. Believe it or not, I've kept track of the number of times I've been asked if I'm the grandmother...21 and counting! Our daughters were adopted domestically and are Caucasian. In fact, even their birthmom comments about how much they resemble my husband. I kid him all the time about "what were you doing in the fall of 2000?" I don't offer the information that they were adopted in casual conversation. People who know us know and occasionally I'll comment on it if the information seems relevant to the conversation. I don't feel like I'm lying - it's just not everyone's business. The girls' adoption story is their story to tell if they choose. (Now if I could just get my Dad to quit telling everyone and their brother on first meeting that the girls were adopted!) If the people in your life who are making comments you find disturbing are close to you, maybe you could talk to them privately and let them know that Lucas's story is HIS. I had to write a very long, involved letter to my FIL instructing him to not ask questions about the girls' adoption in their presence. Told him I'm more than willing to talk to him about it (if it's information I feel comfortable sharing) but that talking about it in front of the girls is disrespectful to them. He took it surprisingly well, considering he and I don't see eye to eye on very many things. Not sure if I've given you anything helpful. But you're not alone!!!
