You know you're old...

We went to a family wedding this weekend, had a great time. My mother, in all her infinite wisdom, said the following:
"Wow, you know you're old when your little brother's kids are getting married."
The Wife: "You mean you didn't feel old having all of your kids married and being a grandmother?"
Mom: "No."
Me: "How about not being able to remember anything, Does that make you feel old?"
Mom: "No."
Apparently, as we age our judgement becomes impaired, along with other things. Something else to look forward to, yay.
