Parents Don't Remember My Face

I havent seen my mom since the day before i left for holidays more than a month ago. i saw my dad about two weeks ago. i dont visit my home very often because i dont know who to visit. my mum, i will just fight with. id go to visit my dad but he doesnt hold a conversation with, even when i invade his study room of privacy. i go there to eat, collect my things, drop off some things. my sister visited recently. my parents went to Myer and saw a girl there with a 'spitting image' of me except without the nose ring. They called out my name to her, they approached her and continued to call her 'Jenny' but the girl, WHO WAS NOT ME, just shook her head. Poor thing, being approached by delusional parents thinking she was their daughter. I think my parents have forgotten what I look like.
