No sex please, you're dossers
Don't go bringing prospective lovers home for a romantic interlude on the sofa. The people whose flat you're staying in are going to sit on that couch. (Though hat-tip to the dosser king, Julian Assange, who has apparently become romantically involved with Pamela Anderson while dossing at the Ecuadorian embassy in London.)
Don't get any dossers
It's bad enough that you're cribbing on someone else's sofa, resist the urge to bring home a dosser of your own.
Know when to walk away
Assange is deep into his fourth London winter as a guest of the Ecuadorians. Decency suggests one week is the perfect length for a doss; a fortnight tops.
Pass it forward
When you do finally get a flat of your own, be generous with the hospitality.
Got a great dossing story from your London days?
