yes i totally agree to the parents favouring the older sibling....
My husband is the older one and his younger one gets treated shit...when i see his situation i can totally compare his with mine as i m the younger one and my parents are totally blind folded.... there was a time when in my teen age i was so bullied by my only sibling 10year elder sister...i tried to commit suicide....i had consumed poison and during the time she got violent and kicked me in the tummy and everywhere....while i was lying on the floor struggling for life.... my mother who was standing beside did do nothing but after 16 years today i still have a lot of grudge against my family for having me go through that shit while i was just 13yrs old...unfortunately today i have an arranged marriage to this man who is just my sister's carbon copy and treats me the same way....u can never fight them back... just forget it...the families are blind folded and never hear anything....no matter what they are always right!
