...when u realize that someone you were talking to was trying... really trying, to annoy you. and is now annoyed themselves. bcoz you didn't get annoyed.
in fact, you didn't even realize the attempt. but then, it's been brought to your attention by a mutual friend. and u're amused, at the most. by how much effort ppl need to put in simply to annoy you. and fail to understand why it would be worth the effort.
what do you do, then? do you...
a. go ahead and remain unaffected... annoying the person who was trying to annoy you.
b. pretend to be annoyed and let the person be happy with their cheap thrills.
hmm... the nonsensical quirks of human beings!
