"Just snap out of it"
"You need to get out more"
"Think of others"

One time I was with a friend and we had a conversation about a decision I was going to have to make that I was not in favor of. The conversation between he and was not going very well. I was at a house where he was living, and just he and I stepped outside to talk. He then got tired of our conversation and said, "let's go in and talk to Shelly (a made up name). She just lost her husband recently. Let's go in and cheer her up. That should get your mind out of yourself."

Needless to say, I never saw that friend ever again. I felt bad about that woman losing her husband. I had the feeling when we went in to talk with Shelly, she seemed like she didn't want to talk at all.
