LOL - yup - we can agree to disagree. I don't know what, exactly, it is with Heather that I find so annoying but you're right - first impressions really are lasting ones. I never watched OLTL when RH was on, but the brief glimpses I saw of him made me not want to watch the show. I couldn't stand him. I also didn't like him on ATWT. Maybe if I'd watched both shows longer, he'd have grown on me, but from what I saw, I couldn't stand his characters. I know many people loved him, but from what I've seen, I really didn't like either of his characters.
I don't know if it's so much that I love Chloe, I just prefer her to Heather. I don't know either of them all that well.
