There is a classic saying that if you make an assumption for others, you make an ass of yourself.
Some people think because they have a certain status or think they do, they like to assume things for others. They think they know you and know you well. So des ne? Is that so? They think they are floating high in clouds by acting this way but actually they are floating in crap; because they make an ass of themselves.
Things change. People change. Some for the worse and some see the light.
Never assume things. If you are not sure then ask. Simple as pie...
If you're the one making an ass of yourself then pull your head out of the bung hole and get a life!
