When someone sends you a message on Instagram, there are a few things you can do to react in a way that is respectful and polite. First, always respond with a smile. This will show that you are happy to receive the message and appreciate the person’s input. If you cannot smile back, try to be understanding and say something like, “I’m sorry I couldn’t understand what you said.” If the person is asking for your opinion or feedback, be sure to give it. It’s important to show that you are interested in what they have to say. Finally, always remember thatInstagram is an app meant for sharing photos and ideas with others. Do not post pictures of yourself or your friends without first getting their permission first!
