Self reflect

hmm... just got some self reflection yesterday... an insight of me...
I don't normally talk much to people. Whenever people try to talk to me, I would just reply with short sentences and will be quite abrupt as well. But this only applicable to people that I don't really click with or not that I think of being very close to me....
I mostly listen...and sometimes lazy to talk to people as well...sometimes it's even very difficult for me to express myself what I wanted to say
and the moment that I had the urge to talk, boy, am I super blunt. Coz I talk too bluntly and too truthful that people might not be able to accept it. You might say I'm insensitive,not being tactful, negatively speaking... but it's just some fact that I conveyed in my message...and sometimes, I really do not know when's not the right time to say all these. and it will be even worse when the person is not in the mood to listen all these...zzz
I just do hope people that have known me that I do not have ill intention of what I've spoken...of coz I would try my best to be tactful and not speak too bluntly...
