The answer is are. We're includes you, and you weren't eating the breakfast, so that cancels out. Is is used for 1 thing/person, so that can't be true, since it could be the cats, then it would be more than one. It's not was, since if it was past tense, then it would be were, not was.

Explanation: No, I wouldn't say people are only complete when they're aware of their ancestral culture. Many people have no idea who their great great great grandma was, or even know she existed. I think a lot of people are focused on the now, and either don't have time, or just wouldn't like knowing. It is a very good thing to be proud of your culture, and where you've come from, but it is not a necessity. You don't need to embrace your culture, or race, to be confident and proud of who you are.
