But, at least in my humble opinion, if you send a text message and do not receive a response within twenty minutes is very likely that you will not receive a response at all. Never. Never ever. Never ever ever. And you got the point again.
Because we're not talking about twenty minutes, of course. We're talking about no response. At all. Nada. Nichts. Niente. Rien de rien.
Now, if you're like me, for you this means that the person does not care to answer. If it's a bad day for you (or just for me?), this can also mean that the person is not interested in you. And I'm not talking about some big relationship. Maybe you sent a text message to a colleague or an acquaintance, just to ask something very 'normal'.
