The more you try and talk/be like someone else the more awkward you will make it. Just talk to them like regular people, you know them.. they are your friends.. so just talk as you normally do and get them to focus on each other. It takes time and practice to find your groove... it is fine having some inspiration on what you want before you go.. but it can be crippling as well. Pressure is all put on by yourself, its for free.. they are getting a gift out of it.. no harm no foul. Locations wise there are heaps... Abbotsford (Quarrantine Park), Bradleys Head, Nielsen Park Vaucluse, Callan Park Rozelle, Ballast Point Park in Balmain, Cockatoo Island, Hunters Hill. It depends on the look you want, where you live, how far you want to travel.
