Yes, it is!!!

When we were in Brunei I had several scans as part of my ante-natal care, and at one of them the sonographer asked if we wanted to know the sex of our baby as she could see it clearly. At that point we were dithering about it so asked her if she would write it down for us in case we decided to find out.

We soon concluded that, on balance, we'd rather have a surprise on the day so we hid the paper and thought no more of it. Well, today we found the paper and... she was right!
