Liz, While Mike could have approached you in a better manner if he wanted to be serious he is a teenage boy and will say dumb things sometimes, but he has a point about Dawn feeling neglected because a boy came into your life. It’s a thing that often happens at the start of a new relationship where existing friends get ignored in favor of the love interest.
It’s a pitch where instead of it knocking your socks off it will be hit all the way to Flanders Field.
