I was really expecting this particular individual to have no cartridge in her knee. Somthing horrific at a young age that could justify such a bold and brash reaction, not pulled or strained ligaments and tendons. If you really wanted to be heard a more tactful approach probably would have suited your situation better. I guess what's done is done though huh?! If a situation is so bad that you are having to try to ignore said individuals (who are FAMILY)
Who have an opposing opinion then You probably didn't have all your ducks in a row :/ I'm truly sorry to hear about your daughter injury but you might want to make sure that your perception of the situation is correct because it sounds to me like a minor injury. The type of stuff you get from going outside. :/
