Who knew

I'd like to beat up whomever it was that said men are sociable animals.
Those who tell me to relax, ease up, wind down, cool off, lighten up. And, of course, the two Chinese girls talking loudly in the IT room where I've taken refuge from my own anti-social tendencies.
Who knew I could be so aggressive? I am not equipped for it, with my thin whitish arms and piano-player hands.
