My mum hates it... She totally flips... It is not something I can control... Whenever there is a charged or anxious moment or when I realize I have made a mistake, I laugh or crack a joke.
We need to understand everybody handles situations differently and there is no correct reaction... There is just reactions.
I have been trying to avoid this, but the amount of flake Rimi is getting for reacting differently... For hiding her feeling behind a laughter is surprising.
Looks like majority of the people have not heard of nervous laughter or of people hiding behind laughter.
Edit
There have been times where I have laughed and yet deep down thinking oh shit. To know ones real reaction to a situation read their eyes.
