- If I miss my turn (gps will renavigate)
- If I can't find the place (I can call them and ask)
- If there's something else I need to get while I'm out (my spouse can call me and tell me)
- My tween, who stayed at home while I ran to the store, has a problem (she can call me)
These are all things (except for the last one) that I experienced without a phone, as a grown adult. And I don't really experience anymore because I have a cell phone on me.
