*nearly misses that, so intent is he on following your hands' rapid movements (too freaking cool, he wishes he understood), but in the next moment his stomach flips over and he realizes he's holding an entire package of frosted, sprinkled cookies (and you're hungry)*
*practically pushes the cookies into your hands, stammering* Here, uhm, I—I have to run, actually. Those're the best cookies ever. I want you to have them. *already backing away, toward the exit* Sorry, it was nice meeting you guys, really, I just. I remembered something I have to... sorry. Have the cookies. Goodluckwiththeflowers.
*practically flees the store, his cheeks burning, stomach twisting with upset* *is a little horrified by the total moron he's just made of himself, but the loudest thought in his head is nothing more complicated or nauseating than please, please, please eat the cookies*
