So, say you’ve made it back to theirs, what constitutes a deal-breaker? Having canvassed opinion from friends of a variety of ages, orientations and professions, the biggest turn off is predictable: a dirty home. Still, where there’s a will there’s a way. One friend told me that when she first met her now husband, his flat was so gross that she arranged for a weekly cleaner to visit. They’ve now been married for 25 years; though sadly the cleaner didn’t go the distance — so repulsed, they feigned a terminal illness in order to avoid coming back (it was only a few months later when they all found themselves in the same cinema queue that the penny dropped).
