Hmm...Being thankful or promoting peace and generosity...while both simultaneously also promote over-indulgence (among other things)... Mm... Let's go with Christmas, because (at least for some companies) it's still one semi-Christian related day that people get off work (if they're lucky).
Sad/Fun fact for everyone... I did a research project over suicide (cha...cheerful right? That's actually on the things the .gov keeps track of, so I had a lot of data...), and Christmas is the highest time for that to happen.
*Public service announcement* Share love with complete strangers...especially on Holidays...sometimes it's when they're the most down.
Alright then...um...what's your most embarrassing/awkward moment?
