I don't hate Pete. I just think he's Not Right for Sam. I'm sure he's a generally very nice guy and he probably genuinely cares about Sam a lot. I think, maybe, he doesn't really understand a few things about Sam, but Sam doesn't seem to really understand a few things about herself either.

And I don't think you should go in and marry a guy when you're not completely sure that it's what you want. But that's just me. And I won't demonize Pete for not being Jack. He's not Jack, and he's not really the one that Sam loves. Hasn't he suffered enough? ^_^
