When a couple is dating, both parties are looking at the actions and language the other person uses and demonstrates to decide if that person is right for them. That’s why many people dress and act their best while on a date – they know they are being judged. If someone doesn’t behave well on a date, you can just imagine how she or he will act when they get to know you better in a relaxed atmosphere. Remember years ago, when I wrote about someone I had dated once, and it was mainly because he insulted his siblings and played nasty joked on his grandmother who was diagnosed with Alzheimer’s. This wasn’t his best behavior. Nothing he said shined a bright light on him. And if this is what he did to his own sister and grandmother, how would he treat mine? How would he treat me if I did something that bothered him? This was a one-and-done date.
