Just to note, Leydenne, I think you're being unfairly judgmental about that. Would you have said the same thing to someone who said they found great joy in playing Fallout 4?
I take it you've seen the Fallout 4 E3 presentation. Todd Howard likely peed himself a little describing Fallout 4, as did many of the audience members after seeing it. That's how excited they were over a game. And there are two sides to every spectrum. It's a bit unfair to welcome one, but not the other.
I, myself, am finding it difficult to play Fallout 4 after being in the same situation OP described. Bethesda games aren't supposed to force feed you like that. Freedom is supposed to be paramount. If I don't want to deal with the dog, it should not be shoved down my throat. That is very clearly unacceptable, and takes a lot of fun and enjoyment out of a roleplaying game since it seems as though Bethesda is outright telling you that you have to play their role and not your own.

But just because they aren't my companion doesn't mean they cease to exist or that we can't cross paths either again.

But I am also a big believer in perspective. Maybe I just don't fly off the handle on things like this - but then, perhaps I have a different perspective than many others when it comes to games and gaming. I don't know.
