My college always did a free , open to the public Thanksgiving dinner the week before . I always thought that was nice . They would also let people take a meal home if someone couldn ' t make it , many times this was homeless people just taking home more food , which I thought was nice <| sep |> Looks like I picked the perfect time to break out the devil ' s cabbage . <| sep |> Sure , not mine . <| sep |> Is going between houses at halftime acceptable ? How are we supposed to know ? If you are spending Thanksgiving at two separate locations , then leaving at half time would seem like the logical decision , but whether or not that ' s acceptable is up to your family not us . <| sep |> Linear algebraic groups are something I know quite a lot about . Do you know a good reference on differential Galois theory that assumes working knowledge of e . g . linear groups and standard Galois theory ?
