This response is a disingenuous cop out, similar to which you have used previously. Did you have any idea what the piggy bank meant before replying?
If you did you should be able and willing to explain. If you didn't then why reply as you did?
So you haven't a clue what it is?
Hint: Albion can answer this without me requesting him to, if he wants to, since he has been tagged twice.
I was interested in the specifics of your answer relating to pre WW2 and the difference in our piggy bank since then.
