I really did the same to my younger sister.. In summers, she used to sleep on roof top with Ammi and Abba. me and my elder sister used to sleep in aangan at ground floor. In vacations, we used to watch TV late night and chhoti always used to disturb by saying ‘cartoon lagao’ 
iss ka maine pakka hal nikala… chhoti used to say’ jab main so jaon to bhai mujhe apne kandhe pe ooper Ammi ke paas chhoR aae’. I used to stand her in between stairs and peeche ‘Main Jinn hoon’ and she screamed like anything. Subh ko mera nashta daant dapat se shroo hota tha
