Well I have actually...
It's sort of been the story of my young self.
I was never really included, not really belonging anywhere within a group in my childhood years..
I was the quiet little grey mouse no one in particular seemed to notice much and most of the time around others I really just felt like I was just there, but not a part of anything.
So my tip to every one out there is to include more. Don't let anyone feel like they're on the outside looking in, because that really hurts!
So reach out and be kind to each other. Don't let anyone be left out.
Most of the time it doesn't take all that much to make someones day a little better.
