Only Democrats can vote in the US Democrat primary,
This is not true. There are multiple states that allow voting in the primary of a party to which you are not registered. You just can't vote in both primaries.
If you like DnD type stuff, He Who Fights With Monsters is about a dude who wakes up in an alternate universe where magic is real. It's pretty great, and 10 books deep.
My kids (18/16) did not get me a present for Christmas. They got gifts for each other, my wife (their step-mom) and their step-sister (with my assistance). Yet still failed to think of getting their father a gift. They both have driver's licenses, cars, and their own money. I'd have been happy with a $2 bag of sour patch kids. Shit, I'd have taken the fucking coal if they just would have remembered.
