Darling Rouying say "Bye bye"!!

Darling Rouying always use the hand sign to say "bye bye" but this morning at the PD's clinic (brought her to see PD as she has running nose), she SAID it out!! She was playing with someone at the clinic and she out of the blue SAID "bye bye" to this other party and this other party was surprised, returned a bye bye to Rouying too. Hooray, Darling! Keep up the good work!
