If I told you are even going to send a message to someone, make sure the message is not a coded message. Make sure the message is clear enough to be understood.
I mean, whenever you are sending someone the message so far is not a morse code or you are not sending a military grade kind of a message, Let your message be clear. Don't use one word to send a message to someone. Even either on Whatsapp or Facebook or any social media app, don't just use one word one. It shows that you're not interested too. It shows that you played on those people.
