This tradition has been passed from father to son for many generations and we have fully embraced it in this household, and it is...
... The expletives that go along with putting up Christmas lights on a Christmas tree.
My father did it, my father-in-law did it, and my husband does it.
Its a fond family tradition passed from father to son, generation after generation.
And it obviously doesn't restrict itself to real or artifical trees. This year, my husband contributed a few choice words to the fact that part of the lights on the PRE-LIT ARTIFICIAL tree aren't lit - because he can't find the plug.
Ah, the fond family memories we create!
