After a less than successful first date, many people are encouraged to go on a second date “just to be sure.” Is this a sensible suggestion? It really depends on why the first date did not go well.
If you found you had nothing in common, or are looking for different things out of life, then there is no point pursuing this match.
If, however, you have much in common, but your dating experience was poor, it is worth considering whether this might be different on a second date. Your date may have had a bad night’s sleep, be dealing with some drama in their lives, or may just have been super-nervous about the first date. It is not uncommon for people to find a second date to be much better than the first. Treat your date how you would want to be treated.
