OK, I'm just being snarky.
I'm at a conference. There's a man at the same table as me who told me yesterday how he deliberately stands to be assertive/aggressive and then moves into people's personal space to intimidate them when they're having a difficult conversation. so, quite an assertive person in general.
Today, he's typing. Not listening to the speaker, but doing his emails etc. He is typing SO HARD that the entire table is wobbling. There are 5 other people at the table, and none of us are typing/writing so hard that the table shakes.
(and yes, I should be listening to the speaker, but he's annoying me so much I have to put this somewhere)
