You may think you know what is best for someone but you don't know everything about them, so you have no idea what is best for them.
You should learn more about someone not base your opinion solely on what you heard about them.
You could have gone through the same challenge as someone else yet it affects each of you differently.
You could be very close to someone for your entire lives yet not know how they feel about everything.
You base what you think would be best for them based on WHO YOU THINK THEY ARE or what you heard about them. But who they REALLY ARE is why you have no idea what is best for them.
Don't let anyone decide what you will do because you and you alone will have to live with the consequences for everything you do.
