KMC Forums - strange coincidince

OK, here it goes:

My cousin in Vermont is adopted and he just turned 18. His parents that have taken care of him have left stuff from his life at the adoption agency every year for his biological mother to check out if she wants. Pictures, report cards, the whole nine yards. Well his mom knew that once he turned 18 she was aloud to look at any of his files in case if she wanted to get in touch with him. His parents actually left her permission before that but she didn't know.

So she goes to the adoption agency to check out his files, where he lives, what he looks like, etc. And she brings her daughter that she kept who was born about 2 years after him. So when they start going through his stuff they find out that he lives in the same exact town as them and that he goes to her daughter's (or his sister's) school. And when they finally look at his recent picture her daughter was like "Oh my god I know that kid thats Patrick Haynes from school!"

Does anyone else think thats weird? He just found out that an associate from school is actually his little sister. I would be freaking out. He went over his real mom's house for dinner tonight and met her for the first time. Keep in mind that the adoption agency isn't even in the town they live in, its about 30 minutes away. The town they live in is so small it doesn't even have an adoption place. It's seriously like a population of 1,000.
