I went costume shopping last night, and made a few choice purchases. Originally, I had planned on dressing up as Buffy the Vampire Slayer, but this idea presented a few problems: How to dress identifiably as Buffy while 1) remaining tznius, 2) not wearing a cross, and 3) not carrying around a stake all night.
So I scrapped the Buffy idea. While I do not want to ruin the surprise by telling you what the costume is going to be, I will reveal the following:
1) I am not dressing up as a platypus
2) I've already had to promise a few friends (none of whom will see me on Purim) to send pictures. Apparently, it's that funny.
