That depends on how BAD the first date went and why it did not go well.
Ask yourself questions like:
Did the date go bad because the other person is someone you do not like or feel is a bad match for you?
Could the person you went out with been suffering from a "bad day" or "bad moment"? or Were you having a "bad day"?
Did the date go badly because of circumstances which were out of either persons' control (ie: pouring down rain, horrible traffic, bad service at a venue)?
I would seriously and honestly consider all of these before deciding if I would try a second date with the same person. If I decided not to date the person again, I would be honest (gently) and let them know the reason(s) for my decision, rather than just avoid the person.
