"Bro"

We took Logan to the park on Saturday.  It was a lovely day.  

That afternoon, he started referring to Zeb as "Bro."  Everything was "okay, Bro," and "sure, Bro."  We thought it was adorable but has no idea where it came from.  So, we asked him.  

Apparently, he fell at the park and an older boy helped him up and cleaned the mulch off of him and that boy called him "bro."  And so it is.

And it just tickles me.
