Yes, when you have a pet like that one!!  We had two dogs, Grommit and Cookie.  Grommit was a lover - he love my son, his master and he loved me and he would just look at us with his big black eyes and you could feel the adoration oozing out of him, but his sister!  Well, she'd drive you nuts for all the demands for attention she'd make on you!  She never relaxes.  Well, Grommit left us about a year ago and it was pretty hard on my son who is 13 for that was his best buddy all his life.  But now that Cookie's on her own, she's finally turning into an old lady and beginning to settle down a bit and she's becoming more bearable now that she gets all the attention she wants.  

But I have to say, Candace, it's hard a times cause Grommit was such a sweet old guy and so laid back and easy going and Cookie just isn't.  She's the watch dog and always on the go doing her job and hard to relax when you'd like her to.  So, I think it all depends on the pet.
