Friendship can be seen. It is seen in an old couple sitting in

the park holding hands. 
Friendship can be heard. It is heard in the words of two friends who meet for lunch. 
Friendship is felt in a touch. It is a pat on the back from a teammate or a hug from a friend or a loved one. It’s a touch that reassures that someone is there, someone who cares.
Friendship has a taste. It tastes like a delicious homemade meal.
Friendship has a smell. It smells like your home when stepping into it after being away for a long time. 
Finally, more than the other senses, friendship is an experience of the heart. It is the language of the heart—a language without words; a language that, whether seen, felt, heard, or tasted, is understood by the heart.
