One thing we don't do is talk to each other during the day. We never did unless it was needed. If I can't make it to the store, I send him an email and he'll pick up whatever.
We cook together, shop together, talk about current events, when he takes a bath I sit on my little bench and we talk. Just chit chat. Then we watch shows we both like. We are and will always be best friends besides husband and wife. Kids are grown and gone. We have a great life together.
Next week he's going to be on vacation. We have small projects planned.
There is nothing I can't talk to him about. Nothing.
