let's take a look at definition of "friend" from my own perspective. when I hear friend, I understand two people granting each other permission to use, take, abuse, etc things that's covered in their interest and it's goes on mutually (but still you're not inside my comfort zone where i can trust my vulnerabilities to you :D ). in uzbek, it's used so damn often cuz this is how uzbek friendship looks like. also, this term can be easily applied on any business. so, are we friends or not?)
