This happened with me recently. I used to chat with my crush. Though he never liked it.
It so happened that I had asked him a very random question related to his dressing sense, he did not like it and so blocked me, I suppose this is the reason, I'm still not sure about that.
I had called him up to thank him for what he did as I had never had any other way to stop texting him.
Later he unblocked me but I dint text on whatsapp. I used to send normal text messages to which he would never reply.
Once again with no other option left I decided to call. I started asking some random questions to which he was answering.
Then,
Me: Your just giving lame answers !!
Him : You are asking lame questions !!
facepalm
I don't remember what I had replied to this.
He was generally a person of few words atleast when talking to me, I would always wonder why he never spoke. And i know that day I regretted for making him talk. I told my friends and they just laughed at me saying I deserved this. One of my friends said “you should be careful when you talk to people like that because you'll not know how they'll respond back to you”.
I finally understood why he chose to remain silent most of the time and let him be that way.
