Eric absolutely did it on purpose!
Even after Ruth said she didn't have a boyfriend, Eric still had the nerve to ask about her boyfriend?! If that wasn't intentional, then what was it?
Ruth was nearly going crazy. "I'm telling you, Eric, are you trying to get yourself killed? Believe me, tomorrow I'll call Sylvia and tell her you harassed me!
"Hmph! Then when she kicks you out of the house, it'll save me some trouble!"
Eric was petrified!
He knew Ruth would probably do something like that.
