Hello,

Are you talking about a bus pass? I bought a day travel card to
continue my travel on the tube inside central London, but the bus route
was actually outside this zone, and the bus stop was on the boarder
between the zones. So, what I realised now, is that I could have
"saved" by buying just a tube return ticket if I wanted to. But thanks
for the question.

I do not need to convince myself about my intentions, but obviously I
am now paranoid about my ability to proove them. I simply cannot
afford thinking that anyone will simply "believe me".

thanks!

R
