Positive Smoking...I mean, Thinking

Me: "You know, let's try and think of something positive about this place. I feel like I've been saying negative things all morning."
Joel: "Okay. *looks around* Well, there's trees, so that's good. Very green."
Me: "Yes, they are very tall. And they provide shade."
Joel: "Yes, and there are different types of trees."
Me: "Uh huh. And the trees provide us with oxygen."
Me: *inhales deeply*, right as smoker passes and lets out an exhale
Me: *COUGH COUGH COUGH* " Ugg! The positive thinking didn't work!!"
