Sometimes there are reasons why people act the way they do. Probably, who knows if you had gone through the same condition, you might have acted same way
Don’t mix bad words with bad mood; you might have several opportunities to change a mood but you’ll never get the opportunity to replace the words you’ve spoken. Hurting someone can be as easy as throwing a stone in the sea but do you have any idea how deep that stone can go?
Respect people’s feelings, even if it doesn’t mean anything to you, it could mean everything to them. How you make others feel says a lot about you. Hurting people hurt others.
Don’t be quick to judge, you need to understand that person’s feelings and thoughts and what they might be going through. Be sensitive to the plight of others. A little consideration, a little thought for others makes all the difference. You are who you are today because of what God’s grace has made you.
