Nobody knows what the person in front of you might be going through. We all have had a past we are not proud of , we have been to bad situations, bad times , have experienced darkness where even our shadow left us alone. Everyone wants to appear presentable in front of others. So when you see someone not being their usual self and stressed. Stop judging them . It must have been difficult for them to have put on that shoe, dress up right , comb their hair and stand in front of you. There are even situations where we can't even imagine ourselves being swapped with that person. Let's not forget this. Let's not make a rude remark that "Oh dude , you look messed up? " . Instead give them a pat on their shoulder and say "You know whatever it is that you are going through would end soon and you will be at a much better place ? " and give them a smile. Let's not bring up the situations that they already are having a hard time dealing with mentally.
KINDNESS IS COOL AND SYMPATHY IS ADMIRABLE.
Have a great day!!!
