You can't make it with only half of the recipe

A mis-understanding can create problems that never existed. Life is hard enough without making things harder on yourself. Make sure you understand things by getting all the facts you need. If you can't find facts to back it up then you have to assume that you misunderstood. You may have heard only part of it but to understand it you need to hear it all. It is better to ask and get all the information needed before you react. Its like hearing only half of a recipes ingredients and cooking it. That's not going to taste any good. It's best to get the entire recipe so you can enjoy it.
