Sorry about that, totally won't do it again.
I was surprised by my own hesitation when I wrote it and did ponder alternatives, wish I'd gone with one of them now.
All the vaguely gender neutral casual terms for strangers all feel like they have a gendered flavour to them for me.. Dude, Bro, Fella... Do you have a preferred term for situations like this?
I'm just gonna edit it to use your name. That's what I'd do IRL.
Sorry again
