Sometimes we just have to put things into their relative context.

I was very cross walking back from the bank. Someone had paid £200 into the wrong bank account without telling me and as a result the one they should have paid into went into overdraft and I was faced with a £200 bank charge.

Then I walked back alongside Westminster Abbey in the dark. Seeing those hundreds of little wooden crosses together made me realise how petty are our little problems compared to the greater sacrifice and sacrifices.
