There is nothing worse when meeting someone for the first time then that akward silence after greeting each other. Kick the silence into orbit with these conversation starters.
How was your day?
You look really nice, where did you get (item in question)?
How was work?
If you are in their home comment on an ornament or a piece of furniture.
Have you seen any movies recently? How did you like it/them?
What kind of music do you listen to?
Ask if they saw a interesting TV program.
What sports do you play or like? How long have you played for?
What did you do this weekend (week)?
Have you been to (a local restaurant)?
What kind of foods do you like?
Where are you from?
Where did you go to school/college?
Have you read any good books lately? Was it interesting?
What do you normally do for fun?
Do you like (an interest of yours)?
These will get the conversation going and you will find out what the other is interested in. Then you'll know if you have anything in common
