Words such as best-friend, bestie, bff and friend have become very popular. In my opinion too popular. When ever I hear someone say any of these words I always wonder how true they are.
I had very few friends until college, maybe about three people at one time or another whom I would call a friend. It wasn't until college that I really knew what that word entitled. My sister recently had a lunch date with her 'friends' including her 'bff' and didn't go because of money. Money has never stopped my friends and I from going out and having a good time. If they don't have the cash than lunch is on me and vice versa. I have the type of friends who send me money (without me asking or even saying a word about it) because my cell is off. I have the type of friends who stay in the hospital with me all night regardless of work and class. My friends have driven 30min back to the dorm to come and get me after they've gotten off work and 30min back to the city because I needed to go to the store. They've let me drive their car to work everyday, when I didn't have my own. They cried as many tears as I did at  my at my brothers and uncles funerals. They have been there and are still there. Money, no money, broken down cars, no car, laughter, sadness, disagreements, death, and life...they are there.  Life happens sometimes (babies, husbands, work, school, family..and disagreements) and we don't talk for weeks and yet we still are devoted to our friendship.
I'm not sure if people know what friendship really is... an extension of your family most times even closer
