Thank you for your help One of my youger cousin sister is claiming that I was not born on 10th of September but 8th. Is the folowing is grammatically correct? Since I remember, my birthday is celebrating on 10th, not 8th. Since she is younger than me how does she claim that it was on 10th. Was she born before i born?
Okay, I see what you're trying to express. However, I would say something like, "I know when my own birthday is; she doesn't." or "How would she know my birth date better than I do; she's even younger than me?"
