No, hon, I didn't mean that YOU were, I meant that THEY are acting more immature. I don't see that there is anything wrong in how you wrote you act. I just meant to say there is something about some of us, myself included big time, that seems "childlike" to many people, but NOT immature, irresponsible or otherwise "Childish" (note diference).
I am so sorry that your boss chose such an unfortunate way to joke about this other lady's talking problem! How humiliating! People don't realize how badly that stuff hurts. they just don't. Pootypoo, I can understand that so well (I can't formulate a sentence straight to save my life sometimes). HUUUGGGS and a nasty stare at your workmates.
