Ser, Estar, and a lot of rules

Esta semana en Español, nos enteramos de "ser" y "estar". Both "ser" and "estar" mean "to be". We learned how to conjugate them and what both are used for. "Ser" is means more of "what" something or someone is and "estar" is "how" something is. Ser is also used in situations concerning permanence, identity, origin or the title of someone. Estar is what is at the moment, is relevant to the well-being of someone, their health, condition and also their present location. Increasingly, I've also been reminded how confusing Spanish is. There are all these rules, but then there are so many exceptions or loopholes to them!
