I have told both my kids that the point of dating is to meet the person you are going to marry. However, one should date different types of people because it is as just as important to find out what you do not like in a potential partner for life as it is what you like. I have also told them that they have plenty of time for dating and their focus at this point should be on their studies.
Any young person coming to my home to pick up my child must meet the parents (or at least one of us) prior to departing on first date.
To my son: Always go to the door and greet parents when picking up date. Escort date to the car and open door for them. Do not honk from the curb. That is disrespectful to date, parents, and neighbors.
To my daughter: You do not run from the house when summoned by a horn. You are not a dog.
I think some dating during high school is okay. Group outings 14/15 individual dating 15/16.
However, my oldest had a summer fling when he was 13 and again at 14. They would meet at the pool. Walk to Dunkin Donuts for a snack. That was about as serious as it got. Last year he had what I would call his first serious girlfriend. It lasted a few months. They would talk all the time, facetime, etc. She came over our house a couple of times and he went there a couple of times. But alas, summer came. She went away to camp and then family vacations. When she returned things were not the same. She was always too busy to get together. My darling boy felt neglected. He broke up with her. Very tragic.
