For me friends don't arise of "we can be friends?"
I think these people are only interested in free drawings.
Also, for me friends are not those who necessarily talk all day and every day with you. They are those who are there for you when you need them (from both sides). When you see a comment from them and you are filled with joy. They are those who you feel a connection to and it is not necessary to explain it by words...
Someone who will always tell you what's right and wrong. Not what you want to hear.
