Why on earth is it the opposite. Is there some law that you must be middle class have a joint income of over £50k and subscribe to the Daily Mail before you have a wedding list.
I remember when a wedding shop went bankrupt and all the brides lost their dresses as I was getting married about then. I spent £600 on my dress which even then seemed like a ridiculous amount of money to me, but we could afford it and it was relatively cheap. Some of the brides and parents were talking about £2000 -£3000 numbers that they had cut right back on everything to afford and were paying in installments.
Some people, god forbid, might not already be living together and have everything they need but may have relied upon the wedding list to get their basic kitchen equipment.
To have no sympathy at all is a bit mean
