Even though your theory CAN be right, you're missing something, if you heard closely in the episode what Lori read on the paper, which was: "To Lori, open immediately". Bobby didn't know that Lori was trying to open the presents only on Christmas morning, so with that in mind, he WOULD have celebrated with his family, but because Lori didn't open it immediately, Bobby couldn't celebrate with his Family.
