Unless you're going to be okay with sharing it, then don't. The whole point of being with family on Thanksgiving is to actually BE with family on Thanksgiving. Even if your family doesn't make the effort, you should try.

You should, as it's quite likely you'll find yourself feeling bored and ignored by your family if what you said is true.
Except if you own a smaller device with internet access.
