<p>I have no incentive to give someone I don’t know well my number for one, what’s in it for me? plus email is simpler. things go directly to spam, and I can delete an email even after I’ve opened it. with a phone, I can’t just hang up on someone as easily, and, to be honest, hearing a ring just to find out it’s nothing is sort of annoying.
even with email, I don’t give it out unless I know the person or unless I have to contact, say, a teacher.</p>
