Difference between a Friend and a Gaali friend

First blog...well first because the others were lame(Hoping against hope this one is not)

So I've had tonnes of friends in my life, i've valued all of them. I haven't always bothered to tell them that but if they did not understand that themselves they weren't really my Gaali friends, yes you read that right....a GALI friend. This is a special category of friends i made, during school, Engineering and my MS. Now that i've introduced you to this tacky sounding term it is imperetive that i explain what i mean by that, so here goes.........

Q: Give scientific differences between a Friend and a gaali friend

A: 1. When you call friends you say hello, when you call the gaali friends you use the foulest word that comes to your mind (Kaisa hai "Insert favourite abuse here")
2. A friend will console you when you're fucked, gaali friend will laugh his ass off because you were stupid (leather seats to my MS "friends"?)
3. A friend will chat with you and call you regularly, a gaali freind will meet you after years but it'll still feel like you met him the day before. (You even do things you did when you met regularly.....i still talk about making life miserable for my engg. teachers when i meet one of my gaali freinds from that age, i still eat at the chinese tapri when i meet my friend from Junior college....i still wanna play CS all night when i meet my MS friends)
4. A friend will know you but when you 'KNOW' someone he is a gaali friend( I know which friend to get drunk when i need maximum entertainment...yes you HellzAngel)
5. A friend will wish you on your birthday, a gaali friend will meet you weeks after your birthday and tell you "Harami mera party kidhar hai?"
6. When you fight with a freind you have to make up....when you fight a gaali friend you will sit over a drink like nothing happened...no one apologises...end of)

I believe this should get me full marks for this question....but i'm sure i'll add some more points to this list.....so to all my Gaali friends who are by now laughing while using some really colourful words....cheers to you!
