That one woman you care so much about. Only she can be Bay Bay. There’s no other like her. Yes she sometimes gets on your nerves but she’s worth it. When she’s upset you better watch out because she doesn’t pull punches. She’s the most beautiful woman you’ll ever come across in life. From the first moment you lay eyes on her your whole entire world will change for the better. She spends all her time working and with her family but she always calls you on her break time because you mean something to her. When you get yourself a Bay Bay don’t ever let her go. Treat her right and always respect her because she’s a Queen. Always support her because she’s focused on accomplishing all her goals and overcoming the obstacles in her way. Be her peace, be her safe space. Love her with your all. Always be her honey.
Darshani is Bay Bay.

Good Morning Bay Bay.
