Although a diamond is pretty, shiny, and has become associated with the highest level of commitment in a relationship, there are others, simpler ways to say "I love you," which deserve attention.

We will briefly explore 3 simplest ways to say "I love you"- as sometimes love is hidden in the smallest of details.

1) A shared experience

"SHARED JOY IS A DOUBLE JOY; SHARED SORROW IS HALF A SORROW" Swedish Proverb

One of the most powerful ways to say "I love you" and "I want to spend time with you" is by sharing experiences. Shared experiences bring people together and enhance each person's individual experience.

A study by Yale University observed that sharing an experience with another person, without communicating, amplifies one's experience - both pleasant and unpleasant. For example, scientists found that even the simplest tasks, when two people ate chocolate, they each described the chocolate more flavorful as opposed to eating the same chocolate alone. 

Imagine sharing a moment, such as a sunset, which is an opportunity to create a history of common meaning. Imagine a shared experience and a discovery, where we create an opportunity for a special bond with a place or feeling. Imagine a shared thought where we create an opportunity for common understanding. Humans are social creatures, and it is within our nature to share.

2) A brush with love

Imagine a sleepover. Whether you leave your toothbrush at your partner's place or it's your partner that decides to give you a new toothbrush prepared for this special moment, we can safely acknowledge that this is not a mere coincidence. If you are not dating yet, it's not so subtle sign that she wants to spend time with you. And if you are already dating, it means that you are not a casual date. 

Because it's this object that symbolizes the first step, the moment when you begin to wonder if those sleepover nights are going to become a regular thing. This is the first act of showing a brief vulnerability bundled in a couple of toothbrushes — this moment when you realize that this relationship might be just more than a casual fling.

3) A key to my place 

Giving a key to your partner could be symbolic, but it is a sign that you both have a good feeling for your future together. It means that you will be there for each other, and you both feel safe. It's a cool next step when you feel happy with your relationship. 

An NYC dating expert Susan Winter sums it up nicely: "The right time to give your partner a key is when you feel completely safe with him or her; emotionally, physically and mentally." It doesn't have to be a big complicated decision — trust your gut and don't rush into anything. Be absolutely sure this is someone who you trust wholeheartedly. If all these pieces fall into place, there's no reason why giving them a key should bring you anything but joy and companionship."

Valentine's Day

According to History Channel, one legend contends that Valentine was a priest who served during the third century in Rome. When Emperor Claudius II decided that single men made better soldiers than those with wives and families, he outlawed marriage for young men. Valentine, realizing the injustice of the decree, defied Claudius and continued to perform marriages for young lovers in secret. When Valentine's actions were discovered, Claudius ordered that he be put to death. It is believed that young couples he secretly wed would visit his cell, passing in flowers and notes through the bars as a symbol of their gratitude. 

The story continues that the condemned father Valentine fell in love with his jailer's daughter. On February 14th, the day he was executed, it is said that he passed the young girl a note. It was signed "from your Valentine."

A tradition was born.
