Code-switching comes naturally. It's not even thought of as mixing languages since most people here know at least two languages, or even three. Tagalog and English are sometimes mixed, like:

• Nakakapagod! Kailangan kong mag-overtime kasi gitpit masyado sa deadlines. (So tiring! I need to do overtime because deadlines are tight.)
• I couldn't submit the paperwork on time kasi na-traffic ako. Ayun, naabutan na ako ng cut-off. (I couldn't submit the paperwork on time because I got stuck in traffic. I wasn't able to make it to the cut-off.)

But with the languages I am learning? Not really, unless I slip up, like when trying to show off: "¡Cuidade! Il ya un perro." I am not even learning Spanish.
