This is something people obsess about all the time.
If you can laugh it must be your happy, or maybe the person laughing found something amusing.
Happiness to me is when nothing in yourself or others can rattle your mood. Solutions can be found for all problems and issues. When we can do this, then we can be happy.
Nobody is without problems or issues to overcome in this crazy life, but if we help each other and understand each other. Anything is possible.
What do you all think.
All the best!!!
