You keep turning down invitations to go out.
Despite staring boredom in the face, you continue to turn town perfectly good opportunities to go out and hang with people. What’s up with that? If you don’t have anything better to do, why aren’t you going to hang out with your friends?
If you don’t see your friends at least once in a while, when you go looking for them one day, they might not be there.
People don’t wait around like they used to and there’s a lot more fake friends than there are real ones. There’s a whole wide world out there and, if you aren’t in it, you are going to remain in a state of chronic boredom forever.
