Things you should never say on a date.

[Lyte]

For the most part and for at least the first few dates... I avoid all the topics that one should avoid in the workplace: religion, politics, sex or past relationships, money, and family or health issues.

Conversely ... I don't usually date someone until I've known them for a little while (ala friendish first) so by the time we get around to dating one or more of the above topics has already come up in conversation.
