@rjmc, where do you live in Portugal? My girlfriend is from ÉvoraI can sort-of, kind-of speak Portuguese but your English is a million times better so I doubt that that will help much...
(I was very pleased for a while that I was no longer the worst speaker of Portuguese in our gang of friends in Lisbon, but sadly the person who spoke it worse than me is now two years old, so she's overtaken me rather rapidly.)
