Is my sister a crybaby ?

My parents woke an I werewoken up in a very unpleasant way this morning,my sister (who is nearly 29 years old) started to scream and cry very loudly,when we went to see what was going on she seemed to be in horrific pain she was holding heer stomach as if she had been shot or stabbed and was moving constantly.We took her to the ER to find out that she was only passing a kidney stone,all this dram for this holly crap !My dad is indulgent to her and agrees that the pain must have been awful,is it really this bad or does she just have a low pain treshold ? No one likes to wake up at 6 am on a sunday especially like this I wish I were an only child.
