Unless you are making plans or something has happened I don't think you should talk to anyone more than one time a day. Also when you are on a date don't talk to your mom on the phone. Its cute but girls want to know that they are the only woman at the moment that has your attention. We all know that your mom is more important but guys just play the role sometime.

I think it is OK for a guy to talk to his mom once a day....Look, we all have one mom and they won't be around forever so talk to them...
