What is the best way to handle the situation if you believe a family friend may have early Altzheimer's Syndrome?

At first I thought he just forgot, but now it’s to the point where it’s freaking me out.

A family friend has been surprised and delighted to notice that we both are left-handed at least SIX times in the last ONE month. He’s only in his mid-fifties. And he’s definitely not joking.

I thought it was kind of funny the second time, a little odd the third time, but now I’m actually concerned.

The problem is I really don’t want to offend anyone, and they’re Argentine and have different cultural customs than mine, so I don’t even know how to approach it in the most polite way possible in their eyes.

I also don’t know if the family already knows.

I feel really awkward about it…
