They must be, they only ever eat my nicest plants. To be fair, though junior is a prime example of highly intelligent but not of this planet. His first week in second year in his own house was a prime case in point. He'd gone out, came home late, couldn't get key into lock ( and no he doesn't drink) , didn't like to wake his housemate up but realising he needed toilet got cab back to campus to the 24 hr learning zone, at which point he remembered that there were no buses back overnight into town and that he could at afford another cab. He sat up all night reading till first bus the next day.
