EBC having trouble walking may have something more to do with circulation problems I'd guess. She's a sizable woman who did have to sit for some time. May have had pins & needles or a dodgy sciatic nerve?? Seems more likely to me than being overcome with emotion & requiring help to walk. :twocents:
MOO
To me, it was more about emotion, she was offered sips of water and had offers to help her out and was clearly visibly 'moved' by seeing her grandchildren. It didn't wash with me though...
