You wait until someone is off the phone. If it is important, spouses have expressions that tell each other if it's more important than what they are currently doing. I learned when I was young you do not interrupt a conversation. Unless it is very important, it is downright rude to interrupt. I don't care who you are.<quoted text>Lets try this in a way edogg can easily understand(hopefully).
Lets say your girlfriend decides to try something new and instead of throwing chairs at you, she sits in one and calls her friend up. While shooting the breeze with her, you walk into the room and have to ask her something. Is it acceptable to you that she simply ignore you and wave you way until she gets off the phone? What if her friend is trying out this sitting in chairs thing also and they are sitting there together, in the same room, talking, and you are not home and give her a call. Are you cool if she lets it go to voicemail cause she's having such a nice conversation and does not want to be interupted by you?
To me, they are all the same act and extremely poor treatment of your spouse and not acceptable.
Now, to completely ignore someone without a gesture (pointer finger up meaning one minute) would not be right. However, the spouse is still rude (unless it is very important) for interrupting.
Eh, different strokes and all that.
I see it as a spouse should already know they are important to each other and should not need constant validation. That's too needy. Not saying you should never validate the importance of one another, however.
