but when she talks to english ppl she knows they cant cant understand it, so she speaks in english,,
her mom and her sisters and me , talk to her in tagalog,, so she really learned it,,its good to have 2 languages u can spaek,, and at least when u go to phils, you will fully aware what they talking about,! yeh ? lol,, hope u learn more and more, good luck !! xx
