if you’re aware enough to give yourself a choice, you can choose to look differently at this fat, dead-eyed, over-made-up lady who just screamed at her kid in the checkout line. Maybe she’s not usually like this. Maybe she’s been up three straight nights holding the hand of a husband who is dying of bone cancer.
Everyone has their own world and their own problems to deal with. Even with our self centered thinking, most of the time we think about others and how the slightest thing could make someone's day such as a small smile. We don't know what a person goes through on a daily basis, but when we interact with each other even for a brief second, we understand that we don't know this person and have to give them the benefit of the doubt even for a brief moment. Using the mom example exemplifies how sometimes we just think about ourselves and have to try to make those brief interactions smooth and easy because we truly don't know what is going on in someone else's head.
