To paraphrase Mrs T, we have become the mother of an adult. :-)
I was 20 years old, I really didn't have a clue about parenting. I thought he'd be lucky to make it through his first year! But he was resilient and I learned and now his childhood is officially over - though he's been a man for years, of course.
I'm very proud of him: he's everything a mother could wish for. It's been a privilege to bring him up and we wish him the very best for his adulthood :-)
HAPPY BIRTHDAY TOM!
