When you have those emotional moments especially on a shoot, it is one of those things whether you wonder if it is professional or not. Do you find that you have to keep your emotions under lock and key?
Then when you post something and the emotions have been running high, you also wonder how the emotion can come across in the post. Some can get it and post that response that you are looking for. Some just read it and wonder what kind of drama you are bringing onto yourself.
My advise to you is to read, pause, then post. You will be able to think through about the event, email, text, or call in question. When you are making those moments that will live forever in the text, make it a heck of a memory. Make it epic.
