DD (nearly 18) has just told me she has a boyfriend, her first. Quite relieved that she's in a relationship, but as a father with an only daughter and having been a teenage boy myself...
Anyway. She is emphatic that I must not: ostentatiously sharpen my meat cleaver at him, force neat whisky down his throat or refer to the many flooded pits and deep watercourses nearby.
Tell me dear vipers, how did your DFs handle this sort of thing?
