Today I set out to delete all those redundant phone numbers that I never called anymore/went out of service/changed/etc.

You realise just how many people you keep in touch with or how many people keep in touch with you. See, I always made it a point to be the best kind of friend. I try to keep in touch with a lot of people but, and to quote the quotable, friendship is a two-way street -- or half-and-half... I go halfway, you go halfway and we meet in the middle for some coffee -- so when they stop putting in the effort, it's time to say adieu.

Then there's the people who you exchange numbers with knowing full well there's nothing to link the two of you and you should have deleted that number the day after but you forgot.

There I was, sifting through my phonebook going "Who the hell are all these people?"
There. I'm a louse when it comes to names.
