If you've been around Cricket, you know she lets you know when she'd like to shake your hand. She puts her paw up and nudges at you if needed. It is a pretty cute gesture. I have experienced multiple times when someone has tried to put their hand out to shake mine and I've missed the mark. If someone is with me, they can nudge my elbow so I know to stick my hand out or at times after a short time the person will reach out and grab my hand. Sometimes I put my hand out first to alleviate the question. Today in church meeting a new lady we were chatting away and she asked about my blindness -- oh, that's why you didn't shake my hand when I put it out.
Sometimes I want to give a hug and wonder if a visual cue would help. I often find myself asking when I feel like I want to give a hug ..are you okay if I give you a hug?
Cricket, of course, is always eager for a hug or shake.
