Is this a coincidence?

Here’s a little one from my children, you judge or maybe you have a similar occurance.
I have twin girls who are coming up to six years old in February. They are now at the age when them and their kindy friends are starting to loose their baby teeth. Heres the thing…..
Sofie is the younger of the twins (one minute) and was the first to loose a tooth. It was here front RIGHT bottom tooth.
Maria lost her tooth just the other day. It was her front bottom LEFT tooth.
Sofie is RIGHT handed, Maria is LEFT handed
