it's cold outside! why do i have to leave then?

awww! today i have to go back to university, i stayed in during the last two days so i had a very long weekend and could stay inside my warm apartment. into the bargain, it just started snowing outside!!! dont get me wrong i really like snow but i dont like the cold-an unhappy combination.
that's why today im wearing a rather comfy combination. after all i have only one class and there i will wear a lab coat, so there is really no reason to dress up.
