Poor boys! That would be the main problem of living at work - colleagues who for some reason can't understand that after work hours, their workplace becomes your home. It's like barging uninvited into someone's living room (or even bedroom). Owen's not the most sensitive person around, so I can see him behaving like that! (Gwen would too, she's blundered in before, but I think Tosh has better manners and would check first.)
