@Theamos,
You can always come clean when the relationship gets serious.
- "I am not really 36, Our relationship is getting important to me now and I want to be honest with you".
- "Hmmm, I am not really a former astronaut" either.
- "I figured that... and I am guessing you weren't really on the team that kill Bin Ladin either?...."
- "uh... no, I was trying to impress you. But you don't really perform infant heart surgery, do you?"
- "No.... I work in the hospital laundry."
- "And your breasts?".
- "Don't be an ass.... I think I love you and I want things to be honest from now on".
- "Ok. From now on."
[.... this rarely ever happens, so there is really no reason to worry.]
