Write about someone who is unfaithful.
What is considered cheating these days? At one time it would simply have been all about sex, jumping into another bed for any kind of fun or in amore innocent take on things seeing someone else, two-timing. Nowadays it is deemed as spending emotional time with someone, particularly at the expense of quality time with a partner and they are upset about it. Chatrooms have a lot more to answer for than simply a bit of banter, you can now be classed as cheating simply by hanging-out with others online. Not sure how that’d playout in a divorce court though.
