What are your words and actions doing?

I talked with a young man a while back and his words have stayed on my mind.   He has withdrawn socially because when he would go out to a store, he saw some stare at him and then call him a meth head loud enough for him to hear.

He's not a meth head. He doesn't do drugs.
He's been through a lot throughout his childhood.
He's suffered a lot of rejection.
He has a lot of pain pent up inside.
Those cruel words casting judgment hurt deeply.
It's caused him to withdraw more.
Be kind. Be friendly.
Don't assume.
Show love, care, and compassion. 
Pray for them.
Life has been rough for so many.
We talk about mental health.
What are your words and actions doing to help someone else's?
Are they helping them heal?
or hurting them more?
A smile and a "hi, how are you?" in passing could make a positive difference.
Let's do better. 
Let's treat others how we want to be treated.
Thank you to those who already do!
