It's hard to remember that everyone you meet is going through something. Sometimes you might think the grumpy cashier at the store is just a bitch, but in reality she's having a terrible day. Even with our friends and family, we have to keep in mind that we don't always know the whole story.
It's easy to think it's your fault or their fault for the awkward/rude/aloof encounter, but it could easily be something running throught their minds as they are here with you in the present.
That's why, as hard as it is, even as I write this, it's best to stay kind to everyone.or at least attempt to be kind. We all have those days.... Like me the other day....
And when it's happening to you, be mindful that it's just a period of time that will pass. It will get better.
