: <--- my response to the couple mentioned in the OP.
My dog can be put in her kennel when she misbehaves or is not associating well with visitors in our home. My dog can be sent to the vet's for a week if we are going on vacation and it would be too difficult to take her along. My dog feeds herself, all I have to do is set down the food and she eats it. My dog is potty trained, all I have to do is open the door and let her outside and she does her business. My dog listens consistently when I say "no," and generally does as she is told. When my dog is tired, she curls up on her bed and goes to sleep.
My son...well....let's see. When he is misbehaving or not dealing well with visitors in our home, we have to deal with the tantrum and misbehavior head on, we cannot simply lock him in his room for the duration of the visit or until the misbehavior ends. When we go on vacation, we cannot send my son to the pediatrician's office to be boarded for a week. My son cannot feed himself. My son is not potty trained. My son does not listen to "no" consistently, and he most certainly doesn't do as he is told all the time
. When my son is tired, he cries/whines/is generally crabby and needs me to hold him and rock him down in a very specific environment, and must sleep with a special blanket in a dark room with white noise.
If my kid were as easy as my dog, I'd have had at least 2 more kids by now. LOL.
