I'm so glad you caught the humor in there. XD I'm always afraid my stories are too depressing, haha. Good to hear a compliment centered around humor. <3
As for getting banished, we learn more about it later, but it happens to waifs when they break a religious or cultural rule. The reason why his parents adopted him is because it's another cultural expectation amongst waifs to take on the child of banished parents. As for why his adoptive parents didn't really like him... well, I'll probably delve more into it later, but this type of thing happens in the real world all the time. A lot of the time, parents who already have biological children will adopt a child, and I don't know what it is, but generally, the parents will not treat that child as well as they treat their biological children, even if they originally intended to. There's a lot of interesting statistics on adopted/fostered children.
And yeah, the carriage part is part of an earlier part. XD I'm also happy you enjoy the third person omniscient POV. I'm always a little worried that people will be put off by it.
Thank you for the thorough critique on this random chapter! I'll be sure to go through and make it clearer that not all waifs are banished, and to reduce the amount of times I sat waif, hehe.
