There are some people who are, shall we say, a wee bit lacking in the art of listening and/or chosing a time to leave.

In sessions, it's not cool to look through your book, send texts or to carry out long conversations during someone else's turn.

It's also not cool to leave immediately after your turn. Best to stay until one other performer has sung a song or played a tune before making your exit. Or better still, leave just before it's your turn.

Alas, I have to hold my hand up and admit I've done all of the above no-nos at one time or another. ;-)
