Actually need not worry what has happened. To be judgmental is human behavior. This is a scientific behavioral process known as selective perception. 80% of time we exhibit this process in our life unaware.
Don't feel perturbed.
Since you have regretted the incident and realized your folly - get up and get ready to face the next challenge of life.
I will narrate a similar incident that happened in my life.
It was the first week of July 2008. I went to a school to collect the Teacher's Registratrion form for my neighbourer as the school is on my way to office. I reached the reception desk in the morning and many people including parents were sitting there to get the form. The school has already started in the last week after the summer vacations.
A man came there and he sat next to me. When the receptionist was somewhat free, he told her to call the class teacher of Class V and Class II. Then he sat next to him on my left side. Since I was feeling bored sitting for the last 15 minutes, I initiated a talk to pass the time. I asked him about his children, in which class they were studying. He remained speechless. Then I asked him whether he is an office goer or has his own business. He again remained mute. I was surprised on his moves. The man sitting on my rigth side was also watching the happening. I initiated a talk with this person on my right side. After formal greeting, immediately we started making judgements about this person who was not responding. I said that he seems to be asocial, mannerless person, thinking himself to be a celebrity, though he seems to be belonging to a mediocre family. The other person commented, that he does not have etiquettes. and probably he has never been to a good school in his life. Gradually we became very sarcastic about him.
In another 10 minutes, both the class teachers of Class II and V came. They asked for the parent who has called them. On telling that he is the father of Neha and Udit, they started shouting at him. They said that the school has opened for the last week and he has not sent his children to the school. They will not be able to cover up the syllabus.
SUDDENLY THIS PERSON STARTED WEEPING. IN A LOW TONE HE SAID THAT HE HAS COME TO INFORM THEM, THAT DURING THE SUMMER VACATIONS, HIS CHILDREN HAVE GONE TO HARIDWAR FOR GANGA ISHNAN AND BOTH OF THEM HAVE DROWNED IN THE STRONG CURRENT OF WATER. THEY ARE NO MORE AS THEIR BODIES HAVE BEEN RECOVERED.
Suddenly there was a pin drop silence in the Reception area. The teachers started crying and so all the parents present in the room. I utterly felt bad about the incident and cursed my snap judgment and selective perception behavior.
WHAT TO SAY MORE.
