Ricky, i'm sorry to hear about your ankle and the subsequent encounter with such a self-centred (insert appropriate swear word here). unfortunately people like that do exist and seem to be able to go through life devoid of empathy and compassion - i believe it's called 'being shallow'. rest assured there are people out there who would stop and help you but please, please don't fall off the curb again to see if you can find one. hope your ankle feels a lot better soon. :)
