Wow, seriously! I'm thinking of a few other names to call him.
I'll give you kudos for not overly apologizing for him. You didn't stick up for him, but explained enough of the situation so that his behavior was his to own. What a cowardly thing to send you in there! WTH!
Hoping next year's return is less complicated. Me? I filed for an extension this year for the 2nd time in my life. I think it's somehow fitting that the first time I filed for an extension was the year we got married (on his insistence) and the next time is the year we will be divorced (also on his insistence). I'm still waiting to see a copy of his W2.
