Grrr I hate people like that. My dad is the same. When I went to the pub quiz yday my dad and his friend make silly jokes about guinea pigs and when I said to my dad I now have 20 and Crater will have hers anytime now and he said "Oh i'm guessing you have that many to make a fur coat!" - Those two also believe guinea pigs have no personality!
The one thing which I stress to everyone when talking about my piggies is how they all have very different personalities. Its great that we have a forum where everybody understands each other!
Mine definately all have very distinct personalities! Thats the one thing about the pigs that really surprised my boyfriend when he first met then and got to get to know them. I've never met two pigs who are quite the same thats for sure!
