This is what I do. I would observe a person first and then approach rather than approaching instantly. I feel this way it is easy to face any rejections or embarrassment.
In order to make friend, I would carry:
A confident look
Be direct in approach
When I finally arrive at the spot with all the tools in my hand I would start the friendship game.
1) The first thing is to introduce myself. Hi! My name is ….?
2) Then if the person introduces him/her self. Good! All you have to do is build a rapport now.
3) If the person doesn’t introduce or shows any signs of hesitation or you sense it, first try… before giving up.
4) In the next attempt… try to find a common interest. Maybe where is the person from, which department he/she works in, share information that could be helpful… “you can find a good eating joint nearby, you can come with me for a match, I buy the children’s book at a discounted price from this place.”
5) If this is difficult the best is to smile and compliment something about the person or that he/she owns. “Wow where did you buy this from it’s looks beautiful…I’ve been looking for it. You have a pleasant smile (As I said I’m very observant and then approach, so I would know a little about the person’s behavior and attitude by now).
These are “my sweet simple and easy approach to making friends”. I have been successful so far. Number doesn’t matter to me. What counts is “even if they are few they should be there forever.”
