Do you know your friends or families phone numbers by heart?

My cell phone died and I needed to call my mom and I couldn’t remember her number. I was thinking to myself wow really, how could I not know my mom’s number, since I knew it before I had a cell phone (which I’ve had for a long time).Then realized it was because I never dialed it anymore I just pushed a button. Times have changed that’s for sure. Am I the only one that doesn’t remember people’s numbers? I know its a silly question but its for discussion as well. Thank you…
