The snot is coming, trust me. Diwali. Halloween. Thanksgiving. Hanukkah. Christmas. Kwanzaa. New Years. Take your pick.
Or just cold weather. Always gets the snot flowing. When I worked in an office, every single year starting in October the whole crew got sick. One came in, passed it to another, and it stayed in play until springtime.
Snotty hands passing files. Snotty hands all using the same copier. Trust me, it's coming.
