I rarely use our cell phone.... yes, we share one phone. But I do have a few personal rules.
1. In the car only if Hubby is driving.
2. NEVER during the playing od the National Anthem, TAPS, or retreat.
3. Never at a funeral.
4. Never at a wedding
5. Never in a church.
6. Never in a Hospital ~ Go outside
7. Never let my friend put me on hold while she yells at her kids ON MY MINUTES. (She has unlimited, I do not) She tried it once and "we got disconnected"
As a matter of fact, very few people have our cell number as we got it for when Hubby is on military assignments. I use the home phone.
