1. Something positive - Begin with a greeting. Talk about something you like about what I have shared.
2. Thoughtful - A comment that will mean something to me to let me know you read/watched or listened to what I had to say. - use any language.
3. Something helpful - Give me some ideas for next time or ask me a question.
Encourage me to make another post
