1. You have to join to the office or you should join to the office? What is the difference between these two sentences? "Have to" is more like "You're required" and is an obligation to do so. "Should" is more like a recommendation or a suggestion to do something. 2. I have requested for your help but you are not ready to help me or I need your help when the time comes but you don't help me. That slimeball doesn't bail one out! 3. Real friends come when we need help, but the fake one goes disappear at the time when we are in trouble. A friend in need is a friend indeed. 4. Some People think they are cleaver but in reality, they are not so clever, when the situation gets difficult they show their stupidity Empty vessels make the most noise or A Backseat Driver. 5. I don't like cagey people, they are not helpful at all they only think about themselves. They don't have any emotions on others feelings who request for help. Someone who is "Full of himself". Just my 2 cents worth.
