Some times there are students, who take your gentle and polite behavior for granted. how do we effectively deal with this problem with out hurting them?especially when they are argumentative and say they are also grown people?

I am in Miami which is a melting pot of people from everywhere. Many of them are immigrants, my question now: have any of you used a system that is successful in targeting them?

Thank you Dr Susan I will try them out

I need a contact management software to manage the school leads, any advise please?
