Here are a few helpful tips from me to you:

1. If you're listening to music at your desk and want to make your pen a microphone so you can pretend to sing into it, make sure none of your co-workers are looking at you first.

2. If you're washing your hands in the bathroom and you still have the song in your head and want to start singing out loud, make sure you are actually alone in there so as to avoid the awkward coughing as a signal to let you know you are in fact not alone.

3. If someone catches you talking to yourself, immediately pretend like you were singing a song and not having a one person conversation. The good news if they caught you doing 1 and 2, they'll probably believe you.

That's all for now. I hope you've all learned a little something about workplace etiquette.
