The man would not stop whistling. What would drive someone to whistle incessantly in such close quarters as economy seating on a trans-atlantic flight?
I was sleeping and “wheeee whut” comes a shrill whistle from the man next to me. Awoken by his misplaced musical inclinations, I’d glare at him until nearly falling asleep again, and the shrill whistle repeats. I think he might have been insane.
The funny thing about whistling is that it really carries. I mean really. And it sounds over any music you might be listening to. Hrmph.

Oh dear goodness, I know exactly how you feel. The three guys in my office whistle INCESSANTLY, and how do you politely ask someone to shut up? They’ll do it in their offices with the doors closed, yet you can hear it all over the entire floor. Ugh. It makes me want to rip my hair out.
