Even if every word of this whole story is true...

...kind, generous, and good-hearted people gave you money for your poor crippled dog that they could have used for their kids' birthdays, and you chose to spend your money on your kid's rather expensive birthday.

Everybody's got important things to save money for and spend money on. I'm sure every poster here with a family wants to feed their family. I think every poster here would be pretty sad if another posters family starved. But people don't post sob stories about their hungry kids to solicit donations to feed their kids and then turn around and spend the money they saved on their food bills to take a family vacation.
