I have about well...I have one childhood friend with whom I will be best friends forever...it seems that no matter how far apart, geographical distance,we are...we are on the same wavelength and when we get together, we just pick up the relationship right where we left it off. if we don't see each other for a year...it really doesn't matter, when we get together...the time that has passed seems like 5 min compared to months. it is never awkward and we never run out of things to talk about.
i have other friends. good friends. people i spend time with. people i talk to. people whom i trust to an extent. it's nice but these people come and go and it's a fact. there's a select few people that one can fully count on.
I'd say in total, about 5 people. That leaves enough room for interpretation.
