напомни обо мне мистеру Сэндфорду

I can't spell without my glasses! I see I've written at one point, "Remember me to you mum!" I mean YOUR! The other person who answered is dead right, maybe it IS old-fashioned and I am a dinosaur... roaming the earth in search of a good pair of spectacles!

It's not old-fashioned to me! And I would not always use them in the same circumstances. For example, to my neighbour I often say "Remember me to you mum." My neighbour and my neighbour's mum are really friendly and chatty, and informal. In our chatty little exchanges 'remember me to your mum' is just the sort of thing we add in. I suppose I might change it to 'give my regards to' ... but I might not. It's just a touch more formal, perhaps. So I'll stick with 'remember me.' Ah! What it is to be from the older generation! What is old-fashioned to some is still as fresh as a daisy to us!

I think this is old fashioned. Today we say: Give my regards to Mrs Sanford.
