since my girlfriend and i can't spend a lot of the christmas period together, we've been getting in the spirit early and this afternoon we decided to build a gingerbread house from one of those pre-baked kits where all you have to do is assemble and decorate.

i love the frosting that comes with these kits. like, i *love* it and i can eat it straight out of the piping bag; it's so good. so, as we were decorating, i was alternating between icing the roof and icing the inside of my mouth. i noticed my mouth was tingling a bit and the frosting had a sort of acidic after-taste but as we'd bought the kit fairly cheaply from the local supermarket, i thought nothing of it and figured it just wasn't as good quality stuff as the one we got last year. 

once we'd finished, i was eating the half a bag that was leftover and decided to pipe some onto my girlfriend's nose. as revenge, she piped a moustache onto my upper lip. i laughed, ate it off and started helping to clean up some of the mess we'd made. everything was fine until i went into the bathroom to wash the sticky remainder off my face and discovered a red 'moustache' above my lips, which had now started to swell.

cut to a few hours later and my skin is still hot and red, i'm sweating and my mouth has that prickly feeling you get when you eat something too-sweet like pineapple. guess i won't be going anywhere tonight.
