Denise: I don’t know that it actually takes (as in needs), but in any event there certainly are all sorts! Working in the garden today, a dog suddenly came woffling up to me – but it wasn’t Tilly.  A couple had come into the garden – my garden! our garden! – not only with their dog, and without asking, but without having it under any control.  They didn’t seem at all concerned when I pointed out that my own labrador was about in the garden, and was on heat.   I’d have felt less annoyed if they had apologized and got their dog under control, but not a bit of it – I had to take Tilly indoors.  How presumptious and inconsiderate can folk be!  It’s lovely having people to come into the garden to buy vegetables and so on, certainly when they seem to appreciate what we do, and I don’t mind spending some time talking, but some folk just make me want to replace the gates in the wall with a drawbridge and watch tower, and put out a sign saying – bugger off!  But then you just need one nice person to come along and it all seems worthwhile again.
