I bet you miss em when they have gone.
I do hope you enjoy your trip down to Heathrow.
Make sure you hit the M25 at the right time and take your guitar incase you don't hit it at the right time. If you get stuck in a traffic jam, you will then be able to get out of the car and entertain everybody.
Used to do the M3/M25 route everyday to get to Watford. I hated it.
Which terminal do you have to get to?
