Do you know anybody who is all business, all the time? I do, and they don’t come off as very fun. However, they may be interesting, like Ron Swanson from Parks and Recreation. The entire cast of Parks and Recreation is incredible, but Swanson is perfect for this example.
He is so hilarious in a joyless way, which makes him even funnier when he freaks out. Although he pretends to not care about other co-workers, he actually cares a great deal about them. Generally, making conclusions about people based on their actions and appearance isn’t the best way to get to know a person. Give people a chance. Maybe they will surprise you the Ron Swanson way.
