You don't need the empty kisses and empty promises from the opposite sex to have a deep connection. There is absolute truth and respect between two who share a mutual feeling. What can disrupt this bond? Sex. However, sex alone cannot ruin the relationship.
Have you ever had a relationship you couldn't explain to anyone else? Your boys don't understand this bond. The rare, small things matter with this person.
I can put it into other words: Instead of offering them the world, you're koo with sitting on a hill together and watching it go by.
"Compare the best of their days
with the worst of your days, you won't win
With your standards so high and your spirits so low
At least remember, this is you on a bad day, you on a pale day."
