I am both overly considerate and a dick.
I have a really common name and am pretty used to getting emails that aren’t meant for me.
For years I’d accumulate email addresses of my doppelgängers and would forward emails to them on the off chance that it was theirs. They are usually really nice and appreciative about it.
Then I got into an argument with one of them who insisted that firstname.lastname[at]gmail was their email address. I was like look you moron. All you have to do is send a test email. Gmail doesn’t differentiate between having a period or not. It all goes to my inbox.
Now I’m a major dick about it and have replied to emails saying I wouldn’t recommend renting an apartment to some idiot who doesn’t know their own email address. (I know which one they are by location.)
