Husband and His Phone

Ma

Normally my husband takes calls outside which is fine. I understand privacy and can be the same way. He just made a call after 9pm (half hour ago) and is still out there, but this time took my car keys and can't be seen anywhere. Is this weird? Thoughts?

****Update: Just to let everyone know, I've taken many calls with people while he was present. He's only done that once or twice. Anyways, his reasoning was to call AT&T; and change our internet plan (?).
