For real 0.o? So which one is American English and which is British English? Or are those the modern usage and the old usage of the word?
It's a complex topic. If you really have to know, you could read up on the topic.
At this stage it would be far easier just to accept that sometimes you'll see a possessive before a gerund , where you might expect the objective case.
... but I don't mind you/your asking.
