I am officially old

My family was sitting around the dining room table, discussing which movie they wanted to watch later this evening. Our youngest mentioned he wanted to see 'Mr. Hobbs Takes A Vacation'. Jimmy Stewart being a big favorite in our house, this was not an uncommon request. My wife commented that our son has been enjoying classic movies lately. Our oldest child then stated, "We could watch 'Short Circuit', that's a classic movie." After my wife and I stopped laughing, my wife told our daughter that she wasn't much older than her when that movie was made.
Not missing a beat, our eldest said, "That's pretty old."
