Even if you think you have all of you i's dotted and your t's crossed, at some point in time something's going to screw up no matter how smart you think you are. I've been burnt by Murphy too many times (maybe that means I'm not terribly smart Jenny) so my input/suggestion, for what it's worth, is:
1-Technology makes us lazy. If she mesmerizes you, (which she does I'm sure) then memorize her number.
2-If you care for her (which I'm sure you do) then delete, delete, delete the trail off the phone!!!
