Yesterday, I set and used an OEP for the first time.

I still feel kind of dirty. No one could have known, but I felt as if
they were all looking at me.

I sympathise. I feel kind of dirty whenever I've used Oyster or a
Travelcard. They're both disgusting, evil concepts that should be
abolished and replaced by very cheap, point-to-point paper tickets
instead. So something like an OEP, which AIUI is some kind of side-
effect of an both Oyster and a Travelcard on it, must feel very, very
disgusting indeed.

And SWT turning traitor and joining the pro-Oyster brigade, means
we'reactually further away from that frabjous day when Oyster and
zonal Travelcards are finally abolished for good. So we'll just have
to go on feeling filthy and unclean every time we use one, Depressing
thought isn't it...?
