Normally when I get a girl’s number, I type it into my own phone and call it to make sure. This time I gave her the phone and left the data entry up to her, which was definitely a mistake. Disadvantage? Pshaw. When you see her again, immediately walk up to her and tell her you want to do a magic trick. Then pull out your phone, pull up her contact info and in your best magician voice say (with a grand smile), “Is THIS your number?†She’ll immediately realize her fuckup and you get to play the “Well, I understand, but…†card.
