Oh the classic dilemmas:
Sack someone in an e-mail or call them in for a meeting?
Break up with your man over e-mail or over text message?
Call your family to let them know about the birth of your daughter or place it on facebook?
Letting your girlfriend fly over and dump her when she gets off the plane or give her a call to say you will fly over as soon as possible and have an honest conversation?
Sometimes though, it is all in the smilies to soften the blow:
I hate you, you are such a dick 🙂
