There's always light at the end of the tunnel
is the thought that was going through my mind as I was sitting in traffic in a very yellow one! ...
...the light at the end of the tunnel is the one of the train that comes against us!
(It's a way of saying) let's hope people understand that they have to stay at home!
You're lucky to still be allowed to do such simple things as leave your home and sit in traffic.
And also to still have traffic around you...
