I just noticed that Anakin talks to R2-D2 in Ep.1 when he's trapped in the cockpit and ultimately takes off...
This is something I always overlooked, but Luke talks to R2-D2 as well in ANH.
How do they understand R2-D2 speak (or droid...)? Is there a translator control readout on the dash or are they just so well versed with droids (Luke worked with and repaired a few and Anakin built C-3PO and worked in Watto's salvage shop) that it is something the audience should take for granted. I just never thought about this and wondered if anyone had any idea.
