Have you ever told someone a piece of information or news and hoped they would pass it along to their family, friends, or significant other? I know I have in the past, and I would always get mad at *that* person for not sharing the information how I wanted them to.
And then I decided that I didn’t like it when people did that to me, so why should I do that to other people or work myself up every time I hope someone does this for me but doesn’t.
If you want a guarantee that someone knows something you want them to know, best idea is to tell them yourself.
I bet this lesson is just a part of life.
