im very annoyed when:
people are gossiping, throwing 'secret' looks at each other, smirking..
people are rude and disrespectful when it is basic courtesy to be respectful towards another, let alone someone of a higher authority..
people are gossiping (again) when they dont even know what we are doing, or spending our time doing..

but for these:
people who asks for help sincerely..
people who are cordial and really very helpful..
people who are friendly but show that they respect you as a person, a senior..

i will continue.
