Those petty sounds that are mood-breakers

• The slurp of taking a 'sip' of coffee/tea and the "aahhh" after the sip
• The 'glug', glug', glug' of drinking water from the bottle
• The smacking, chewing and biting on those evening snacks, with mouth wide open
• The sound of people non-rhythmically tapping their work stations, arousing the thinking cells!
• ...

Common as they may seem, but some can be highly irritating for some people. 

But the positive side of all this? It teaches patience and temper control!

... and I'm learning, BIG TIME!
