Is it appropriate for an adult to announce her own graduation?

I am 45 years old, married with six children, working full time, and I just completed my Masters degree (with a 4.0 gpa). I am participating in the graduation ceremony this December and I want to purchase announcements and send them out to my family and close friends, but my husband thinks this is a silly thing for an adult and a graduate student to do. I guess it is a little braggy, but then again, it's a big accomplishment; one I am quite proud of, and I think I'm entitled to some bragging rights. Is it gauche to send out announcements at my age, or is it appropriate in this case?
