Instant messages shared between friends and sent via mobile phones or computers, offer immediate solutions to getting stuff off your chest.
Be wary of the fact that they can be recorded, given permanence and used by people who want to rock your boat.
The trouble is, it can actually feel quite liberating to write about how you’re feeling to a voiceless chum. When you’re having a bad day, the temptation to let off steam can be overwhelming.
If you’re being particularly derisory about your ex, consider whether you would post the same message on the outside wall of their parent’s house, or splash it across the counter of your local post office, or paint it in the playground of a nearby school?
Instant messages can hold infamous last words that spread faster than the flu.
