Wow the opinion police are starting the year out in full force telling folks what they can or cannot think.
I don't know if I'd say 'frail' but he does definitely look somehow 'different'. To me it seemed his mouth was at bit different, in a way that a family member of mine's does after they had a stroke. (Relax, I'm not saying he had a stroke, I'm saying a member of my family did and was left with a slightly crooked smile afterwards). Maybe it's the paleness of his skin color compared to before that's different
The proof will be in the pudding and when he makes his first public appearance.
I would love it if he were to start answering questions on Twitter again!
