Who is Tim - take 2

We had sort of taken it for granted when Sandra had introduced us to Tim, our sat-nav guy.  So we were a bit concerned when Sandra said:

'I hope his name is Tim!'

kind of hoping that she was right because we kind of liked the name Tim for our wee guy.  So we went looking, and after browsing through the multitude of options we found out his real name:

'His name is actually Sean, but we shall call him Tim'
Elín

and so for the rest of the trip he was Sean, affectionately called Tim!!!
