I heard this for years while the show was running. I refused to watch the show as well. I decided to start watching it recently.

It turns out that what people were referring to when they likened me to Sheldon was my autistic traits. Sheldon incorporates a lot of specific autistic traits in his character and I am autistic. The funny thing is, one of the people that was constantly comparing me to Sheldon was a good friend of mine who was also autistic but I guess she is somewhere else on the spectrum which is why it was easier for her to associate me with Sheldon than herself.

I guess my point is to tell you that sometimes people make uneducated guesses and comparisons that may end up seeming funny when you realize why they made them. Watch the show. Laugh at them for comparing you to an exaggerated TV persona because you were different from what they expect the average person to be.
