My husband can be bad for this. Biggest case in point:

My husband and I (8 months pregnant with our first) were in a T-bone accident on our way back from visiting my family (5 hours south of where we and his parents live). My husband walked away with basically no injuries, I had bruising and scrapes, etc, wouldn't have gone to the hospital but got ambulanced because of the baby, just to be sure.

My husband sent a picture text of the wrecked car (he's a car guy, his dad too) and that I was on the way to the hospital. That's it. His phone then died, and of course he had no charger or way to charge.

His mom was absolutely frantic. They didn't even know which city we were in, because I they knew we were travelling back that day. She tried contacting me, of course, but I wasn't looking at my phone for the first hour and a half or so, because it also had low battery and I was busy being checked out. She ended up phoning her brother, who lives 10 min from my parents, to get him to look up their farm phone. My dad, who had been receiving updates through my mom, was able to reassure her that her son wasn't hurt, and it didn't seem like I or the baby had anything major but we were being checked/monitored for a few hours.
