I have lots of acquaintences as havoc says, girls, guys. True friends maybe 1 or 2, but I dont think that true friends need always be around you, but more so they are always there if you need an opinion or help.
If I left my job, I think this figure would be greatly reduced, friends come and go, true friends are hard to find, thats why its important to live your life for yourself and not the people around you.
Thats what I have always believed in anyhow
