Blind people, you ever have a conversation like this with someone?

'Guess who?'
'Um, no idea. Where do I know you from?'
'you must know me. Come on.'
'No, not that I can think of.'
'You don't know this voice? Come on you know this voice.'
'Really, I have no idea.'
'I knew you from when you was a baby you know? Me and your mum (or dad) used to be like that!'
'OK... Still don't know.'

Hate conversations like that. they expect you to know who they are after a double-figure amount of years, like it was just yesterday. Why?
