We have been looking at controversial topics and for the sake of avoiding arguments, we decided to avoid the typical topics of bull fighting etc. We decided to look at the influence of the Internet on our social lives and specifically looked at idioms (expressions) related to the internet and communication.
to be a big mouth – not be able to keep a secret
to come clean – to tell the truth
to tell tales – grass/tell on someone
to get the wrong end of the stick – misunderstand
to catch someone´s drift – understand what someone means
