Cẩn thận để che giấu biz của tôi

So, I need to finish this little gadget that pulls your hair out instead of shaving it,

because I did it in the dark last night, and therefore there's lots that I missed.

So I'm out in my car before I head over to my guy's house, finishing this up,

because it's embarrassing to do it at night, being too quiet.

And I'm in my car, I've got the blinds up, and I've got a curtain on the side so nobody can see me.
