What is the meaning of FRIEND ?

The older I get, the more I don't understand  the word friend. You call your acquaintance a friend? I don't and we are not acquaintance.
Why on earth, that you received a message from me and you didn't even bother to read... yes read not even reply?
Why that you want get my phone number ? To me, the meaning of you getting my phone number is that you want  to communicate with me.... Why you want my phone number, when you didn't even bother to read my message? I don't understand.
But on the other hand, when you want find people to talk to, you will come and talk to me. What am i to you? Am I not a friend ? If your answer is yes of course, you are a friend to me but WHY you did not read my message? That's the cruelty of Whatapp.
I am not the type of person that have 100o million of of message send to you everyday. Just check your phone, how many message that I have send you so far...

Disappointed.

Can someone tell me, It this a new era, that you have different meaning for the word FRIEND ?What on earth is happening ?

P/S: Yes, there is anger is my writing... but I wont amend it .... This is what I feel right now!
