This is a tough issue. I am closer to my co-workers than most of my family, so I think that telling them isn't going to be a big deal. I know several women who are having 'work' (breast augmentation:ohmy:, tummy tuck:smile2:, etc.) done during Spring Break, so everyone is discussing everything pretty openly.
My biggest wrestle right now is whether or not to tell my students, or rather, how to tell them. I am a middle school choir director - my students question me every time my hairstyle changes and they could probably tell you the clothes that I wear most often - right now, it's a small list b/c nothing fits. My students know that I am an open book - they are allowed to ask me anything (we stay on appropriate topics, mind you). I have 5 girls in choir that are my same size (26-28) - 12-13 year olds! I want to be sure that I say things correctly, and still remain a good role model. Plus, I am never absent from work - in the last 130+ days of school, I have been gone 5 days, all school business. They will know something's happening. I am thinking about waiting till the day before the surgery, that's when I usually tell them (if I am going to be absent). Actually, my students will probably be my largest cheering section - kids are resilient that way!
Whatever happens - I am READY for a life change!!!!!
