Friendships and relationships are an investment. They are not effortless, they do not magically flow or mesh.
You don't just magically wake up 40 years later and find them still going strong, neither do you just throw money at them and hope they last 70 years.
You need to invest time, energy, effort,love and most importantly the very essence of yourself into them.
If you don't put in the work, then don't expect to reap anything but empty and dry bitterness.
