Sit somewhere and listen for 15 minutes. What do you hear? What's going on around you?

Here is what I heard sitting for 15 minutes in my living room:

• Hoban licking himself
• Cars coming off or going onto the drive
• Someone sneeze outside my window
• A door open in my hall
• My own breathing, soft
• A truck backing up somewhere near enough that I can hear, but far enough away that it's faint
• My clothes rubbing together and against my couch as I adjusted myself
• Typing (okay it was me doing this, but it still counts)
• A mechanical squeak from outside I couldn't identify (perhaps wheels on a shopping cart? Honestly, it sounded a bit like a swing, but that doesn't make any sense. Seriously, this squeak kept happening)
• Hoban's tags jingle
• Hoban catching his plastic bone that has little ghosts on it (yes I was throwing it)
• The sound of my fingers scratching at my scalp (yes, they were mine)
• My computer humming quietly
• A child delightfully calling out
• An adult cooing
• A child babbling
• The creak of a gate opening
• A car horn sounding just once
• The door of a car closing
• My fingers running through my hair
• A car horn sounding louder, more annoyed
• An airplane flying overhead
• Two car doors close in quick succession
• A metallic bang that I couldn't idenitfy
• A motorcycle revving
• What sounded like a vacuum in the alley 
• Steps on the broken glass by the curb
• Another truck backing up faintly
