I would not expect you to comprehend why I don’t rush to make friends, as I understand the significance of gradually forming lasting friendships.
I do not make it a requirement that you have to reciprocate my efforts before you can become my friend.
I can not expect you to rush to my side when I am having a challenging time, because you are busy.
I would not want you to see my tears and feel my pains because you may be uncomfortable and not know what to do.
As a friend, you would not require me to explain all the above in the first place, as it should come naturally if you truly are my quality friend.
