Somehow, at 28 years old, I have finally become an adult in my mother’s eyes.
I was talking to her on the phone and she made lascivious comments about a young man at her health club. She actually said, “If I were thirty years younger…”
(To which I almost replied, “Heck, Mom, who needs to be 30 years younger? You just need to be unmarried.”)
She has never done this before. She and my father are happily married, so it’s not like she’s dating or anything and testing my reaction.
No, I can only assume that my mother sees me as an equal now. I blame my marriage. After all, it was at my wedding shower that all my Mom’s friends asked me to call them by their first names, when they’ve never asked that of my 34-year-old unmarried sister.
Marriage has its perqs, and my sister hates me for it. 
Ohh. Who’s the lucky fellow?
And here I am like a dope thinking you’re announcing your 18th or 21st or 25th and a halfth birthday. 
Thanks for the OP, now I have “The Pursuit of Happiness” song going through my head!
“Well, I don’t hate my parents
I don’t get drunk just to spite them
I’ve got my own reasons to drink now
Think I’ll call my dad up and invite him”
TPOH, “I’m an adult now”
And I was all ready to say that anybody who feels the need to announce their adulthood obviously isn’t there yet, but never mind THAT. Ya see, on my twelfth birthday, I announced to my mom that I was no longer a child, therefore establishing my childishness. sigh
And last year (when I was 24) my mom quit having pretend heart attacks at the thought of my getting married and having kids (not that either is likely right now). Now, THAT was WEIRD. She must think I’m more mature than I do! Yikes!
