This is true tragedy, in every sense of the word. Every 16-year-old will think that they're too cool for their birthday, and that hanging out with their lame family and eating some lame cake is, like, the lamest. They'd totally rather be out chucking up a mixture of In-N-Out and Jägermeister into the bushes while their friends take pictures and send them to everyone in their contacts.
Except that really isn't the case. Everyone, even the hardest teenager, secretly loves their birthdays and the fact that their mom baked a cake just for them. They love that their family is dorky and sweet and always remembers them. So when that symbol of the family love slides right off the platter and on to the floor... well, that's true tragedy at its finest.
