Fun fact: there's tons of office romances, and people fuck like rabbits while working in the same company all the time. Even in puritanical US (or especially there).

Heck, millions of people met at work and finally got married.

And, no, flirting is not the same as harassment.

My brain wasn't sure how to compute seeing the phrase "fuck like rabbits" right next to use of the work "heck" instead of "hell."

LOL, foreigner, so I just use "heck" as a common idiom -- not because of some puritan upbringing.
