Really, whether it's a lie or not... it is absolutely no one's business unless you desire to share your private and personal information. Everyone's coworkers, family etc. are different, and while some will be thrilled for you, others will scoff and it and stab you in the back with depreciating gossip. Personally I don't give a hoot if someone feels negative about it. I am nearly 100 lbs lighter than I was a year ago so they can stick it where the sun doesn't shine (hehe). Most of those people are just jealous anyhow. But, unless I want to tell someone, it is soooo not their business.
