I feel old, but not in a bad way
My co-worker and I went for coffee, not an uncommon thing since there's a starbucks on every corner. We took along a young chippie from the company that bought us who is very nice but awfully young. She lives a life full of adventures like getting drunk and passing out on a regular basis, hitting the weed in the afternoons and many other things that I too did when I was a bit younger, though I don't seem to remember doing them quite as often. I suspect that she's been awfully young for most of her life, despite occassionally being around people of her own age. During the 15 minute adventure, we had to remind her to use her inside voice, got comments about how square we were, us geezers. Finally I said 'I feel so old around you' and she said 'I'm sorry'. My response? It's not really a bad thing.

My buddy said it isn't so bad, being thought of as a square, it leaves your social calendar wide open.
