It just seems to me that if he lied when the truth wasn't even a deal-breaker, how would he act in the future when there may actually be something at stake to lie about. (Not future episodes, but future life.)
Any correction of this lie in the future better include a big apology from him for letting it out there and not immediately correcting it -- NOT a glossover with an excuse of 'oh it just wasn't a good topic for first conversation'. The only thing worse than a lie is a guy who tries to excuse it, or convince you his lying is okay.
Consider "Shooter". Now there's a guy who--when given a perfect opportunity to lie--blurted out the truth instead. Regardless of whether or not it cost him his shot on TV and his shot at love, the truth just propelled itself out there I'd take Shooter (a guy who can't help but tell the truth) over a guy who's dishonest. Shooter's problem can be corrected easily. And 10 years down the road, honesty is so dam_ respectful!
Everybody's different, but I don't think any good relationship can be formed when the first conversation includes a needless lie. Past experience with liars tells me IT'S NOT WORTH IT. Hopefully this guy will prove me wrong though.
