I hate lying Es - it's something that really really upsets me.
Perhaps look at it in context - was it hurtful/malicious. Is it a pattern? It's a difficult one. I mean you could be upset about it - but if it's trully not such a huge thing, should you get upset, but then small lies lead to bigger lies.
Personally I don't think I'd make an issue out of it if it was like - Does your wife feed you & he says no, when you do, 'cos he wants to score some free chow at home.....if it's something bigger - you need to talk it over.
Communication is key!
