We always laughed a lot. Sometimes my laughter was paradoxical, and my therapists would point that out.

Have you ever started laughing and just couldn't make yourself stop? In fact, the more you try to get yourself to stop, the more impossible it gets? It sometimes isn't at all about what initially started the laughter, it's almost as if it becomes involuntary. When it happens to me I actually end up in tears. Wonder if that might be what happened to your therapist in that moment.
