Dilemma

If someone that I talked to for a grand total of 3 times back in school wants me to add him as my friend on Orkut, should I accept or decline? I don't want to add people to my friends list just for the sake of having 80 people on my list even though we've never considered each other to be friends. If I decline, then I feel like I'm being rude.

Why would people even do this? To pretend they have an ungodly number of friends? What is the point?
