<p>When our kids were little we set up a code that they could call home and tell us they were not feeling well and could we come get them. That was to let us know that something was off wherever they were and were not comfortable. As they got cell phones, before driving, that turned into texting. When they started driving that code became what looked like a butt dial (but a pre arranged butt dial) and that was our signal to text them that they needed to come home. We also told the kids that they could use us as an excuse why they couldn’t do something and we NEVER talked curfew in front of friends so if they wanted to leave early they could just say “my parents said we had to be home by 10:00” or whatever. Fortunately we never needed those but the kids liked that they had an easy out.</p>
