At work directions: Plug in your headphones. Go for it.
Alternate work directions if one does not have headphones: Turn speaker on as such such. I am recommending a 3 (indoor voice) but you might want to start a one or two (whispered gossip voice) and work your way up. You decide.
Directions if you are my aunt jean or anyone related to me some other way: Might be best for you to skip this one. . . ;)
Other international advertising that I heart.
