This one was completely overheard at the bar on Friday, but super awesome.
At the bar, there was a hippie girl (sort of a theme for the day I guess) who I was talking to for a little while about music general philosophy (don't ask) on Friday night. At some point I went inside to get a beer and overheard this little transaction between the hippie girl and my lovely wife.
my lovely wife: "...I hate that guy."
hippie girl: "you shouldn't live with hate. Hate is a terrible thing."
my lovely wife: "I'm starting to hate you, too."
I dunno, I thought it was very funny at the time.
