She really can't pronounce her name so, bright tita tried to teach her one syllable at a time by repetition:
Tita shouts, "lulu!", she replies "lulu!."
Then tita shouts, "wiwi!", she replies with a grin, "wiwi!"
Then tita thinks this is it so she shouts, "Lui!"
She then replies (again with wider grin..), "Iyo!"
Nyehehe. Sabi ko nga eh.
