Vacation trips are magic carpet rides into different worlds. I think we have a primordial need to possess at least a little piece of that magic.
The good news is that it is not your fault if you carry home something useless, ugly or embarrassing.
Look at the choices you have in the souvenir shop.
The cup and saucer.
The seashell thingy.
The wooden plaque.
It's even worse now. In earlier souvenir shopping days, everything was not made in China.
