The hashtag #IFeelOldWhen is trending on Twitter today and the tweets are incredibly hilarious.

Some of my favorites were:

"#IFeelOldWhen my kid watched a VHS tape for the first time and couldn't find the "Main Menu" button on the remote"

"#IFeelOldWhen someone asks me if I'm 'getting some' and I think they mean sleep"

"#IFeelOldWhen I have to make a second trip to the store to get what I forgot to get the first time."

"#IFeelOldWhen I find an ancient looking coin and it's dated the year I graduated High School."
