I might be a ltitle less strict with letting my dragons run around, but often when I'm on the computer in the living room here, Scout will get restless and jump off my lap and run around the living room. normally he runs over to one of the windows, jumps up and just sits there, looking outside or glassdancing to get out(he does this a lot more when it's sunny outside, but too cold for him to go outside), or he'll go find a nice dark corner to cuddle up and sleep.
I don't watch him really though. I'll turn around and see if I can spot him, if not, I'll get up to track him down, and if he's cuddled up somewhere safe(AKA not behind the TV like he tries to get) then I'll leave him or let him cuddle under my jacket or blanket.
My older sis is completely in charge of Riza(the only reason I'd be considered 'partial owner', is because I paid for her mostly, but I don't do any husbandry stuff with her.) and normally lets her run around her room. Riza normally goes under the bed or on the window too.
