Be the character
If you imagine yourself in the same place that your character is in, you can place yourself in the moment. Placing yourself in the moment can help prevent writing something awkward down. Would that really happen if I was doing it right now? Would she really say that? How would someone react? Would they shrug it off or get mad? What are some minor details I may be noticing? Birds singing? The heat? Or is it chilly air conditioning?
Being the character can also make it more interesting for you, too.
