Imagine you’re a bus driver. Your job is to keep driving forward to each destination, stopping once in a while to pick up passengers. The passengers that come aboard aren’t chosen by you. Some are nice, many are neutral; a few are a real pain. Regardless of the mixed bag, you have to carry on moving forward. The passengers will always be there, doing their thing.
Even if you could stop the bus and throw out the nuisances, it’d take a lot of time, you’d fall behind on where you need to go, and you’d be exhausted by the end of each day. Leaving the passengers alone as they are, pretty soon the irritating ones get off at their stop. They might return, but it’s OK – you can keep focusing on the job at hand.
