I'l be on the phone with her and not know what to talk about. If I don't say any thing in less than 3 min. she will make something up. I really love her but I don't know how to prove my love to her, with out her getting mad at me.

You should tell her just that. I love you but I am having a really hard time proving it. Why do you find it so hard to talk on the phone to her? Why do you think she would get mad?

On your computer, record your mom calling you from the other room and just play it when you feel like you're in trouble and need to get off the phone.

It takes a while to learn how to ask questions on the phone so that is sounds like you're talking when you're just asking good questions it takes her awhile to answer.
