Are you one of those people that keep numbers stored in your phone even when you haven't heard from someone in months or years? Is it for sentimental reasons? Do you hold on to those numbers in hopes of hearing from that person again one day, or because you may want to get in contact with them again; or are you just too lazy to go through your contact list to delete them?
I prefer to have as few contacts as possible because I don't like long lists so if I have anyone's number I'm mostly going to be in contact with them frequently. If not I just delete them or not even have their number usually. There are, however, a select few people I haven't spoken to in months maybe years but I can't bring myself to delete their number .
