Do you even remember the numbers you're calling?

I always remember the phone numbers that I use the most but a phone notebook always comes handy so in case something happens to the phone you will not lose all that information.

Yeah, ever since I have a cellphone, I stored all the numbers in the phone, and I hardly remember any of my friends' numbers. I still can remember their house phone numbers where I memorized them before having a cellphone. But, I can remember my family's phone numbers. Well, I gotta force myself to memorize them. Just in case if any emergency case happens, and I don't have my cellphone with me, at least I still can call one of my family members for help.
