We are all humans and we can not be all the time the same. We change along the day, we change along the hour, and we change along the all time we live. We can be happy, sad and happy again.
We are not all autism suffering. That’s why it is normal to be different. If you are different from a moment to another that does not necessary means you have behavior disorder.
And if you have a disorder you can allow to be different from time to time. It is normal. You ar not a picture on a wall always smiling. It is your right to be furios but do not hurt anybody.
