Oh I had this when I bought my 3 bed semi alone.
I have a noisy/disruptive hobby and planned to use the smallest room as a soundproofed studio, the conservatory as a home office/classroom for private tutoring and the remaining spare room for friends/family visiting, a lodger if times got hard financially or for fostering/adopting a child.
"What do you need all this space for?"
"Wow. This is the same size as OUR house and we've got two adults and two kids in it...How much is your mortgage and how are you going to pay it alone? Did you get help or something? Wouldn't you rather have house shared? You'd probably have felt safer in a flat instead of a FAMILY home."
My favourite;
"Aren't you scared living here without a man? I'd be scared in a house alone without a man. Sometimes you need a man. You can have my husband whenever you need him, we're worried about you, have already discussed it between usand have agreed you need him."
It was a housing estate...my neighbour on the other side of the wall was a man, I had two men living next door and another who was already keeping an eye on the opposite side if for some bizarre reason I needed a man's protection in the middle of the night. I didn't need 24 hour usage of a friend's husband who lived 30 minutes away!
