Context: I may or may not have mentioned that I ' ve had an occasional allergy to mosquito bites since I was a kid . Hit me at the right time and in the right place , and you might be rewarded by watching my hand swell up so much you ca n't see the tendons on the back of my hand . It was with the knowledge of my occasional allergy that I ' ve been going inside a bit early on these excellent summer nights instead of running around with the kids . Hell , ordinarily I 'd take the swelling to hang out with them , but this Friday I ' m giving a talk at the Detroit / Windsor International Film Festival 's Tech Fair on adapting films to video games , and I did n't want to be all puffy for that .
