well Doc love did mention that, when you call a chick on her cell, she could probably be out, doing something, being buzy with her friends and she wouldn't pay you full attention to what you are saying, like she would if you catch her at home. It does make some sense.
There are a few times when someone calls on my cell phone, and I can't hear them because of traffic, I am too distracted by driving and pay half attension, or sometimes I get cut off in the middle because of poor reception. All that nonesense disappear when I talk from home.
