Nearly six years ago a classmate said one thoughtful sentence to me, is it ok to friend them on facebook?

She wasn’t my friend. I didn’t know her except as a passing acquaintance. She was kind to me despite my surely dim countenance.

It did make an impression on me. I am only just beginning to understand how to be a complete person. I feel like if I could go back I would have made more come of it.

Maybe I should just keep it right there. Just meditate on that one helpful thought she shared and share the same with others.
