this is embarassing..
i was at the pantry a moment ago. as usual, the pantry's dispenser was out of hot water. so, i filled up the flask and boiled the water. my boss happened to be at the pantry waiting for hot water too.
after minutes, the water boiled. the boss was talking to another colleague. so i thought its nice to help them to fill up their mugs. when i poured the water into my boss' mug, the whole tea-bag along with the string and everything went into the cup.
how great to start my day!
