Run’s in the family
Some children are the same as their parents, some are completely different, it all depends on genes we guess. For example, two athletic parents could have a very uncoordinated child together or two bookworms could have a kid that’s all about sports. There are no rules when it comes to kids you got.
But in this case, it would seem that this mother is proud to hear that her son has inherited their family’s lack of athletic ability. Now she doesn’t have to spend hours out in the cold and rain watching soccer practice or a baseball game. She really dodged a bullet on that one.
