...but the differences being you (probably) had an education yourself once, any one of us could be disabled at any time through no fault of our own, and one day we'll all need facilities for the elderly.
Dog ownership is usually voluntary.
Dog ownership is usually voluntary, but so is using the local park. I don't use it but should those that do pay more because of the grass cutting, bin emptying etc. Should I pay more because the Countryside or Highways departments maintain some pathways that most don't use but I choose to. Maybe it's extremes, but there's always some things that one group of people choose to use whilst others don't.
Don't get me wrong, I'm not having a go, but as you may have guessed I'm a dog owner, but I like to think I'm quite a responsible one.
