It's incredibly annoying ( specially for someone with poor hearing like me and no one really wants to watch you chew while you talk LOL) and I'm willing to bet you're entirely right... ALL THE TIME... amal must have given up on being annoyed by it by now cause he knows it's never going to stop XD
I love them. Their expressions are great and so candid here, though I have to say that that's always been a strong point with your work. Now I just ponder what they could possibly be talking about. Love these boys.
