Vertimas - Portugalų-Anglų - você é muito gostoso

Hi goncin

We could also say "You are very tasty" But I will validate your translation as it is

Hi, Ruth! Thanks!

Call someone "gostoso(a)" in Portuguese is bold and often sounds impolite. Maybe the best word to translate it wouldn't be suitable for an underage audience, so I just opted to keep things within the acceptable boundaries.
