"You have been identified as a talented individual and your feedback is very important, so please take the time to share your views. "
Then invited again to register for a survey....
Well 3 of us have registered once....
I would hazard an educated guess that it's son who is the talented one

but who knows... is this a follow up to the initial thing - but as far as I remember that just asked for age + how often you trained. Perhaps they are now trawling a slightly different data base?
If the other 2 e mails don't come through telling us that we're all talented perhaps I'd better e mail back and ask who they want!
