We hurt people by being too busy. Too busy to notice their needs. Too busy to drop that note of comfort or encouragement or assurance of love. Too busy to listen when someone needs to talk. Too busy to care.
If people are kicking you in the behind, at least you're in front of them.
Be careful before leaving someone in a sorrowing situation. Say a word of prayer with them and share even a brief word of encouragement from the Scriptures.
