"those Guylian jobbies? The ones that are different sea shell shapes but which are in fact all the same"

Those are often the ones my well-meaning relatives give me. I usually find an occasion to pass them on to someone I don't mind offending, and usually they at least seem to be delighted.
I have had other supposedly Belgian chocolates that were merely disappointing rather than something to be got rid of.

Something else I find very disappointing is white chocolate. They have taken out everything I like about chocolate, leaving a kind of 'candy' that I really don't want to eat. Another unwanted gift to be passed on to the next unsuspecting aunt or in-law.
