If you need to make a call from your car and the reception is bad, you might be tempted to take the protective case off your phone.
If you give in to temptation and take the protective case off your phone, you might get out of the car before putting the protective case back on.
If you don't put the protective case back on, your phone could slip out of your hand onto the driveway when you get out of your car. If your phone slips out of your hand in the driveway when you get out of your car, it might look like this:
If your phone looks like this, your husband has had to use packing tape to hold it together. If you have a shattered phone being held together by packing tape, it might not work the way it's supposed to. If your phone is shattered and doesn't work the way it's supposed to, you might be frustrated and VERY upset with yourself. Don't take the protective case off your phone. Enough said :-(
