a compliment about what you saw on him recently is a good one, or asking a question, or maybe even complaining about something that would get him interested in the conversation but it really depends on the guy.
well if you sit by him and he dosn't talk to you start a conversation
No
Hello.
Maybe: Can I borrow your pen/cell phone? You have a little something on your cheek. Or just stick to eye contact. If he wants a conversation he'll start one.
yes! it shows your bold. i start conversations with my guy-friends all the time!
Start with "Hi"; and tell him you like his shirt (or whatever) and as him where he got it.If that doesn't start a conversation then you aren't trying.
You say hello, and to whom am I speaking. Then you start on any topic.
lack of confidence
just be yourself start a conversation
Start a conversation and then ask him if he has a date yet.
One way to start the conversation is to ask how he is doing. You could also ask him how his day was and what he will be doing tomorrow.
Try to bring sports in.
