What do Politicians Do When the Opposition Speaks?

Here we are in Germany. The Bundestag discusses the budget for the coming year.
It is not a break. Time to be attentive as Sahra Wagenknecht from the left wing party gives her point of view.

Staring at the phone or in the air, calling in, getting up and wandering about the area or even having a conversation with others whereas someone gives a lecture, is a sign of disrespect and bad behaviour.
