"Ahoy matey! Asynchronous programming be like havin' a crew o' pirates workin' on different tasks at the same time. Ye see, instead o' waitin' for one task to be completed before startin' the next, we can have multiple tasks runnin' at once. It be like havin' me crew hoistin' the sails while others be swabbin' the deck and loadin' the cannons. Each task be workin' independently, but they all be contributin' to the overall success o' the ship. And just like how me crew communicates with each other to make sure everything be runnin' smoothly, asynchronous programming uses callbacks and promises to coordinate the different tasks and make sure they all be finished in the right order. Arrr, it be a powerful tool for any programmer lookin' to optimize their code and make it run faster.\n"
"Ahoy mateys! Let me tell ye about asynchronous programming, arrr! \n",
"\n",
"Ye see, in the world of programming, sometimes we need to wait for things to happen before we can move on to the next task. But with asynchronous programming, we can keep working on other tasks while we wait for those things to happen. \n",
"\n",
"It's like when we're sailing the high seas and we need to wait for the wind to change direction. We don't just sit there twiddling our thumbs, do we? No, we keep busy with other tasks like repairing the ship or checking the maps. \n",
"\n",
"In programming, we use something called callbacks or promises to keep track of those things we're waiting for. And while we wait for those callbacks or promises to be fulfilled, we can keep working on other parts of our code. \n",
"\n",
"So, me hearties, asynchronous programming is like being a pirate on the high seas, always ready to tackle the next task while we wait for the winds to change. Arrr!\n"

"The system message can be used to prime the assistant with different personalities or behaviors.\n",
"\n",
"However, the model does not generally pay as much attention to the system message, and therefore we recommend placing important instructions in the user message instead."
"Sure! Fractions are a way of representing a part of a whole. The top number of a fraction is called the numerator, and it represents how many parts of the whole we are talking about. The bottom number is called the denominator, and it represents how many equal parts the whole is divided into.\n",
"For example, if we have a pizza that is divided into 8 equal slices, and we take 3 slices, we can represent that as the fraction 3/8. The numerator is 3 because we took 3 slices, and the denominator is 8 because the pizza was divided into 8 slices.\n",
"\n",
"To add or subtract fractions, we need to have a common denominator. This means that the denominators of the fractions need to be the same. To do this, we can find the least common multiple (LCM) of the denominators and then convert each fraction to an equivalent fraction with the LCM as the denominator.\n",
"To multiply fractions, we simply multiply the numerators together and the denominators together. To divide fractions, we multiply the first fraction by the reciprocal of the second fraction (flip the second fraction upside down).\n",
"Now, here's a question to check for understanding: If we have a pizza that is divided into 12 equal slices, and we take 4 slices, what is the fraction that represents how much of the pizza we took?\n"
