Dopplenamer

I got my updated shot at the drug store. Some delay at the counter because another fellow who had an appointment at the same time has the same name as me, with one vowel changed. (Is there a term for that - doppleganger for names?) Woman at the counter seemed to have assumed that one of the two appointments was a misprint, then surprised to find out otherwise. I'd known there was someone in the area with a similar name, but had never before met him. It turns out hes' 102 years old (!) - though he could easily pass for 20 years younger.
