Ishaan:-Attention everyone..As u all know today is my Bhabhi's birthday so I want to say a few words for her...
She is the most notorious person when it comes to doing fun..the most clever person when it comes to do planning against me...
But wait guys that's not all...
She is the most supportive person when it comes to facing a problem...the most wise person when it comes to handle family and kids...and most loving and caring when it comes to her family...
She might be my Bhabhi but I can bet that even if I had a real sister she might not be as good and loving as Naira is...
I just want to say one thing to u Jungli Billi...
I might call u Jungli Billi for fun but deep inside my heart I Love u more than I would have loved my real sister...
You are lifeline of our whole family and no one from us can live without u...
We love u a lot Naira..
