I have the rarer luxury of an early gmail address with a first initial last name prefix. Lately I’ve been getting emails for things like trip confirmations, flight confirmations, appliance repair receipts, medication ready for pickup emails. The person is clearly on the side of the country and shares a common last name for where they live. Anyway, turns out it’s an older gentleman who shares my same first initial and same last name. For whatever reason he signs up with my email address. Not sure what to do because I don’t have a way to reach him.
