With other parents, we spend a lot of time in the park after school. This is where some of us take our late afternoon work-related calls, or socialise with other families, or hide behind our laptops, while the kids are playing.

Some hard-working parents will prefer to send their kids to the park with the nanny. The issue with many nannies is that they often don't have children themselves, and in most cases, that's precisely why they are hired for the job! You can very easily tell which nanny has kids, and which one has not.
