Sounds like she's jealous, I too was told this by my co worker " so I hear your taking the easy way out and cheating to loose weight." Now I still hadn't even told him I was getting it done (but figured word would get around it always dose) so I had to give him a quick lesson and some what brutal lesson in the sleeve, told him all the sacrifices I would be doing plus all the risk I would be taking and how it's more of a tool, so I ended with "if u could afford it I'm sure u would have it done too"
Now I know i was brutal with my last comment but i work in construction if u don't dish it out they will eat you alive, my coworkers actually used to make fun of a guy that had to have a hernia repair done not for having a hernia but for getting it repaired
