I don't know if I did good or bad :( I called the police department to come and check on her because her cell phone was not responding right now.

I am afraid she may be upset about that visit (or she may not be at home right now - I think she is teaching at that time). So, I may accidentally send a policeman while only the kid is at home :(

Should I call them again and explain that she may not be at home right now?

He called me back, said no one is at home at the moment (which is true as she may be at work right now).
