It is very easy to convince your parents to get you a pet to play with. Even if you have a strong will about taking good care of the pet, it is relatively challenging to abide by it.
Once you get a pet, for the first few days or even a few weeks, you seem to take really good care of the little one and even feel proud of taking up their responsibility. But as time goes by, it is human nature to get bored of doing the same thing repeatedly, especially if a child takes care of the pet for whom it's nothing but a new toy to play with.
It is the responsibility of the parents to either not give in to their child's request of having a pet and if they can't help but buy them a pet, then be responsible for them because they are living creatures after all. Once you think you cannot take good care of the pet or are uncomfortable with you, the best thing to do is give it away to someone who would take good care of the pet.
You can visit them occasionally, but once you give away the pet, it is entirely unfair and unjustified to ask to take back the pet again.
It is pretty sad to see that the parents cared about their child's unnecessary rant for a hamster that he couldn't even care for more than the hamster's life itself. Share this story with friends and family, especially those with a pet, and tell them to stand up for a voiceless living creature because they cannot do it for themselves.
