Pretty well normal human behavior.

I've always thought Drupal was a nasty CMS - probably as that's the first impression I was given by someone who introduced me to Joomla :)

Well, having worked with Joomla for quite a while now, I've come to realise that Joomla isn't really the best CMS when it comes to quality components and, more importantly, a robust and configurable Shopping Cart. Yeah that's a big call I know but this realisation has come about once I happened to actually look further into what Drupal had to offer.
