There are many ways to get rid of used items. You can try to sell them online, or hold a yard sale. Sometimes, if you don't think the items are worth much, you can simply put them in your alleyway. It's surprising how often your "junk" will find its way into other hands. (And if it doesn't, you can call the trash company for a "large item pickup.")
This scene reminded me of another "alleyway" full of someone else's junk-turned-into-treasures, from my recent trip to Paris.
