Re: a thought
The only people that really enjoy it are probably the young children
Not so. Around here we still celebrate "Christmas" (our non-Christian status notwithstanding), and we enjoy the hell out of it. Family, friends, food, decorations, gifts, cards, inane holiday music, more decorations, stockings hung by the chimney with care, hilariously tacky outdoor decorations, a fire in the grate and snow drifting down outside1, real fucking Christmas tree2, more gifts, Rankin-Bass and A Christmas Story, good god who bought all these freaking gifts, hey some more friends just dropped by style of Christmas, is what I'm saying.
Perhaps my anecdote doesn't beat your anecdote, but it's certainly not true that "the only people that really enjoy it are ... the young children". In a little more than a month I'll be hauling that tree home and standing it up in the living room, and it'll be five weeks3 of peace at home and goodwill to everyone within range.
And you know what? Every damn year the sun comes back. I'm not 100% certain it's because we do right by the solstice, but it can't hurt.
1Snowfall amounts may vary. We've had decent luck most years, though.
2Frasier fir, cut down by my own hand, naturally. Don't settle for less.
3Or thereabouts; we leave the tree decorated and up through Twelfth Night. Longer than that seems gratuitous.
