he's running away.... sarcastically

I just noticed a new sign on porters door.... He obviously put this up the other day when he was mad at us about something and said he was going to New York. We gave him our blessing and said have fun! Given that he was upset when he was "running away" for whatever indecencies we were imposing on him, I'm not sure if the first part should be read with sarcasm or not. He is his parents son, after all.

(I did ask if he was being for real about us being a great parent and he seemed baffled that it could mean anything other than what he wrote... so I'm assuming he wasn't being sarcastic. Whew!)
