Have you ever caught yourself saying or thinking, "I remember when...?"?

I did not think I was that old, but I have found myself more and more recently thinking I remember when.

Today when I was getting gas, “I remember when gas was $1 a gallon.”
When sending a letter, “I remember when stamps were 12 cents.”
When buying groceries, “I remember when bread cost 50 cents and milk $1 a gallon.”

Those are all money related things, but I also remember when kids used to spend their summer outside playing in the yard, my neighbors would tell my parents when I did something I should not (instead of calling the police), and when we slept on a futon in the living room which became our couch during the day because we could not afford furniture.
