Hmm. I wear contacts so only use my glasses round the house but they are ALWAYS falling off my face! I hate tight glasses so I get nice comfy wide frames, but everytime I do anything energetic like housework or even tying my shoes they slide halfway off

Back to the OP, I think you're reading way too much into this. I know how easy that is too! But really, like someone else said, I bet she just was making sure you didn't both get sidetracked into talking about the glasses, rather than whatever it was you were originally discussing.
