Today, I asked my coworker if he had seen a mobile cart that my team uses at my job recently, since it is mobile, I often have to walk around and look for it.
The mobile cart happened to be right on the other side of him, and I just didn't see it.
(Note that I have glasses that I don't wear often because the prescription is out of date and they don't help that much. I should probably get new glasses).
Being the snarky just-out-of-high-school kid he is, he jokingly said something like, "You're getting old and can't see."
Really? Just really? Kids these days!
I'm taking this all in good fun, and letting him know that in just four years he could have terrible eyesight like an old person like me. Ha!
It's slightly sad to know I'm at the point in life where young people know I'm older than them by several years. When did that happen exactly? I'm not quite sure, because not long ago I had people asking me if I was in high school, or if I was 12. (I don't think I really ever actually looked 12, but some people equate height with age.)
When did you know that you had reached a new stage of "old?"
（Even if the"old" we're talking about is really quite young.)
Twenty-four is definitely still young, in my opinion!
