Law school Hey people! One more day at the law school. Today we studied the obrigations of the society. For example: when do you make a contract with somebody else, obrigations are made for yourself and for the other person. And do you have to do what the contract says or suffer the consequencies. Shure, that only happend if the contract have been made with all the valid requests. That was my law class today. See you.

When we use the "s" at the end of verbs? like: uses, wants... please give examples

There is so much informall use the abreviations like: "there`s" "I`m" "We`re"?

There`s any difference between: "I said that I`m great" and "I said I`m great" That happends because in Portuguese we use a lot of "that". And so I think that could be wrong in English. Thanks
