Mother surprised by filmer and his girlfriend

Note: I have lived in Indonesia for the past 5 years and have not returned home A month before this video, my sister told my Mum that she and her partner were getting married. My sister requested my mum NOT to tell me because I was not invited. The truth is my GF and I flew to Sydney, Australia and surprised my mum and told her that it is me getting married... Not my sister. 2 nights before this video. I spoke with my Mum on a video call so she knew I was in Indonesia.
