I really appreciate people who are not afraid to openly show their love for one another. I believe this gives people hope that true love is alive and well. I believe PDAs act as a kind of mirror back to others, giving them an opportunity to learn something about themselves and/or to inspire others to openly show their love as well. In and of itself expressing love releases happy chemicals into the body allowing anything from a warm glow to pure ecstasy. I appreciate that my wife, Debbi is so free with compliments and PDAs.
