Dd has a friend who she likes but she frequently gets upset about seemingly nothing in particular. She will suddenly start crying, drop her head and refuses to communicate with anyone. This girl is very quiet and almost whispers most form of communication but does have a laugh and joke with her friends. Dd just has no idea how to help when she is in one of these moments, does anyone have any advice or experience with this kind of situation, perhaps phrases or things that DD can do to help?
