What is friendship?

what does a real friendship actually means?
as u guys know, i lost a friend recently.. and i had been reminiscing about him alot..
so i wondered what does a real friendship has to have?
- the moments that we cherish 4ever?
- the bond we have?
- the sweet talk we do?
- the jokes we share?
- the similar thoughts we share?
- the attributes we like about each other?
- the things we share?
this were some of the things i did not get to share with him..
i only got to know him for 2 yrs.. and we weren't as close as we shud have been..
and i deeply regret not knowin him any better..
i have been hanging out alot with my friends these days.
and i hope i do not have to regret again..
