Think of the last conversation you thought was boring: the last person you quickly found conversationally deploring. What made you come to that conclusion? Take these next statements as a warning.
The self serving thoughts of “This person is strange” and “These conversations are lame” are an indicator of your self confirming loss: Loss of friendship and growth in the message of the cross. The same cross that makes sinners worth the cost. That cost that was paid for by Christ so that we may not be lost; may not be found wanting, but so that we may love without condition. And from this point we find our greatest commision. But we do not take orders well. So with blue blood in our veins we resort to vanity calamity. We call others boring and lame.
Confirmation bias becomes your 6th sense. Thinking of yourself in relation to others seems reasonable so long as you keep them in a well generalized fence. Parameters of socio-economic class like “They don’t have cash” and so you live past them because you are faster than them.
If you find yourself bored every time you are in a room of people you do not know, perhaps they are not the cause. Look for the least common denominator. When you realize it is you do not expect applause. Your generalizations are not new.
You could continue to blame that boredom on others, but there is a better way to kick that conundrum. It is astoundingly better to take in simple joy, than to use judgemental fire as a time killing toy. The awful excuse that “you are either extremely excited or terribly uninterested” merely points to the fact that you are selfish. Do not blame who you are on your circumstantial inheritance.

Look to make each person feel the love and interest you feel you so righteously deserve. Look to do a good turn daily. Look past your pride, wants, and even needs. You do not have to be a Boy Scout to do good. That action of doing good requires you to make others heard. That action of making others heard requires you to leave the burden of proof to them and not you. Do not make yourself the judge and ruler of who is cool.
Boredom is selfish. We choose to learn and know as much as we want. Do not stop learning about people and who they are for shallow reasons like, “Are they driving a specific car?” Letting people be heard by listening to them is not the end goal though. It is from this point that we recognize the inherit value each person has being formed by the Potters hand. His mold is perfect and has been eternally planned.
All glory is deserved by God alone. When this is viewed as our main aim, as our only sustainable claim, then you will see that no one is boring. Your chief end is to be actively along for the ride, enter into doxology, and give glory to the most High.
