I'm moving 286 miles in 20 days and I don't plan on telling anyone
What would make you want to keep your moving a secret?
I'm annoyed from being questioned from others about trivial matters, so I think I'll keep it a secret.
If you are planning on moving almost 300 miles away, it is inconsiderate not to let the people around you know about it. Keeping a secret like this builds distrust with others.
Everyone deserves to be kept in the dark sometimes. You can't always go around telling everyone everything. I like to have some mystery about my life.
Usually when people move they tell others. Not saying anything will cause people to worry about you.
