This is how cell phones can be bad.  One summer a child under my care got dehydrated on a hot day after drinking nothing but soda all day.  I took them to the camp nurse who took their temp and it was 100.3.  So we hydrated them and took them back to their tent to sleep.  About 20 minutes after I settle them in, my cell phone rings, it’s the child’s parents all upset.  The camper had called them from their tent to tell them they were sick and their temp was 103.0  So they wanted to know why their child wasn’t still at the nurse’s office and why they weren’t called.  Once I explained the reality of what was really happening they were much calmer.  The nurse said 100.3; the child moved the decimal and heard 103 in their mind.  If they hadn’t had a cell phone, this whole misunderstanding won’t have occurred.
