I guess my early years as a military wife spoiled me for civilian life, because if I misbehaved in any way, as in any complaints reached my husband’s CO, he was the one who suffered for my behavior, not me. Music too loud, trashy looking lawn, driving to fast on base, not me...him.
So I’ve spent my entire life being aware of how my behavior affects other people. If I were a smoker (and I was, once upon a time) and I was visiting a person who didn’t smoke, I would not smoke around them, nor even ask if they minded if I smoked. I would wait until I was on my way home and then light up.
We’ve already discussed the dog-thing, but music is the same way. I won’t even play music while I’m driving if I have a passenger I haven’t seen in a while. Or maybe just a passenger. Music interferes with conversation.
If I’m a passenger with someone who has music on, I sit in silence, responding to any conversational overtures with, “Huh.” If I’m talking to someone and they switch music on, I stop in mid-sentence.
