Q. A bunch of my friends are trying to organize a blog carnival where people can show pictures of themselves eating salad while looking sadly at a snapshot they’ve taped to the balsamic vinegar cruet, showing their sponsored African child, who will be getting an extra $12 from saved grocery bills this month. They’re calling it The 100% Represent and Repent Lent Event 2015 Y’All, and I’m fairly sure they are turning a profit in some way. How can they live with themselves?
