I once suffered a bad fall that resulted in scratched palms and scraped knees. I remember how badly it stung, the cold air hitting my bleeding wounds; I felt that I couldn’t stand up for the pain. Through a veil of tears, I recall a kind hand reaching for me and helping me to my feet. My knees and palms were washed clean, and I remember thinking that for the rest of my life, I wanted to help people stand back up.
