I don't understand why you two cant talk over the phone though

Yes she has a baby, but does it really have to sleep in complete and utter silence?

I'm sorry I don't get it, the no phone call during nap time baffles me... Surely she can speak in a different room if need be?

I try to avoid having any important convos via text, things such as intonation are too easily misinterpreted, and then unnecessary misunderstandings and arguments ensue.
