Welocme back! You missed the scorching heat.
When I want to avoid unpacking, I just do it little by little. I put the suitcase/bag/whatever somewhere out of the way (like under a table) and only take stuff out of it when I need it. I wear it, wash it and then put it in the wardrobe. Sooner or later the whole transfer is complete with minimal effort. You could try this. If you're lazy enough. :P
