I did not see a joke, I see you commenting that you may have been thinking about getting contacts because your glasses fall off. Okay, so? If I wanted to talk about whether I should get contacts or not, I would try to be more direct. If the comment were not about getting contacts then I don't see how to connect to it; not knowing what you and your T have been discussing, it could be about God/religion? I often say things without nouns and my husband does not let me get away with that.

I think if you are embarrassed because your glasses fall off, you have to say something like, "How embarrassing, my glasses fell off." What is going on in our heads cannot be known to anyone not inside our head :-) I do not think we can use shorthand comments and expect other people to pick up on what we mean. Not everyone is embarrassed by their glasses falling off, it is usually not that big a deal for me and if it were, I'd do something about it? I do not think your T had a clue that you were embarrassed, hence no comment. T did not so much not react to what you thought of as a joke, she did not get it.
