It seems ridiculous to decorate for fall

Yesterday was the official beginning of that season AFTER summer, known as fall, or autumn.  Mother Nature clearly didn't get the memo.  Summer is OVER.  Today's high temperature?  Ninety degrees...a full fifteen degrees above normal.  I would be completely okay with fifteen degrees below normal, but noooooo.  It seems completely ridiculous to get out my cozy fall decorations at this point!
