"This hurts me more than anything else in my life. To not know someone I love (my son, my granddaughter, an old family friend) when they are not where they belong. I can not think about not knowing my little granddaughter when I saw her in town without unbelievable heart ache."
I can't say it's ever bothered me in that way. My family are all aware that I struggle with recognising anyone, so they wouldn't take it personally. I just get a few jokes from time to time! Does your family know you have difficulties with faces? I'm sure they wouldn't be upset by it if they know it's just the way your brain works. Children especially are very accepting once they know what the problem is. My cousin is now over the one year old mark and judges me entirely on my behaviour once I start interacting with her (after I recognise her) and not before. And she isn't even aware of prosopagnosia. I think her little brain just assumes I have a problem with sight (which I suppose is indirectly true) so I get waved at a lot!
