Nanny: My mum wants to come and see Pob. She's very excited.
Me: [puzzled look]
Nanny: Yes, she'll be uncontrollable when [boyfriend] and I have kids
Me: [non committal grunt]
Nanny: Of course it won't be easy for us. We will need treatment to get pregnant
Me: [enquiring grunt]
Nanny: Yes, I have polycystic ovaries and [boyfriend] has low sperm count
Me thinking: Blimey, I managed to hire the infertile nanny. Who knew?
