Lesson learned the hard way

Never give your technologically-challenged/phobic mother a cell phone for "her safety".

At first, she won't want to use it because she's afraid of it, and will spend countless frustrating hours on the phone with you trying to get it to work.

Then, once she DOES get it to work and gets comfortable with it, she'll take it into the bathroom with her in case she falls while in the shower, and spill something on it, causing said phone NOT to work. Then, you will spend more countless frustrating hours trying to figure out what's wrong with it, at which point she'll FINALLY tell you that she spilled something on it.

And, if that's not bad enough, she THEN will decide that, until her cell phone gets fixed/replaced, she doesn't want to drive anywhere alone without it, in case something happens to her while driving.
