Go-arounds are a fact of life. The reasons are too numerous to list and speculation in this case is pointless. However, I will stick my neck out on this one. A good flight crew performs a go-around and has another go instead of putting up with something which may make landing unsafe. The next bit is the initial part of the manoeuvre itself. Most aircraft, especially twins, go up like a rocket on a go-around as it's usually performed with full power (to start with, anyway). So you have to keep your wits about you. And I'm afraid speaking to passengers is the last thing on the list. To do so would have added more flight time because you would have to do this in a 'slack' period which would have meant creating a time buffer where it would have been possible for one person to fly and the other to speak. Being radar vectored at low altitude and setting an aircraft up for an approach is not the time you fly single pilot.
So you should feel happy that you were being flown by 'proper' pilots.
