Let's see, what about....
January? -- No, December-January is just as bad as November-December....besides, too many people are hung over from the New Year.
February? -- No, it already has Groundhog, Valentine's, and Presidents' Days....
March? -- No! All those St. Patrick's Day
April? -- No, April is tricky, sometimes there's Easter and sometimes there isn't. Too hard to keep track of! (Maybe that's why there is April Fool's Day!!)
May?? -- No, NO, a thousand times NO! Those stingy boys just don't know how to share!
June? -- Don't be silly, that's for MY birthday!
July? -- Uh-uh, that is for the whole country's birthday!!
August? -- Hmmm, maybe August??? Well, no, everybody is on vacation and it's usually too darn hot!
September? -- No, that's when the kids go back to school and they are generally too darned grumpy to be either thankful or merry!
October?? -- No, Halloween! All those ghosties and ghoulies would frighten Santa's reindeer!!
Nove.... -- Oh, that's right back where we started. Well, darn!
Sooooo, Thanksgiving evidently cannot be anytime except November and Christmas has permanently claimed December. Oh Bah! Humbug! Sigh....
I withdraw the suggestion. Carry on.....
