Annoying Personality

After fraternize with some of my friends, I sum up some personality that I dislike from people.
First, sensitive person. Whenever I am with this person, I have to be careful with my words. I am a sagittarius and I talk bluntly. It's like whatever I say to them is wrong, and they get hurt. They get offended easily. I prefer to be quiet then.
Second, nosy person. I had this kind of situation : I was having fun chit chat with my friends and then suddenly my uninvited friend came to us, sat there, listened and the ambiance got awkward abruptly. Well.. I thinks it's better if the person who comes to us is talkative or extrovert one. What are you doing come to a group suddenly and just listen the whole thing? Are you a spy?
Third, liar. I believe everybody in this world hate this type. But still, depends on each individual. There are some kind people who still giving them another chances after they are deceived. For me, I will mention it again, I am a sagittarius and I will not give a second chance for a liar. I will not trust a liar forever and ever again. If a liar confides in me, my role play will be turned on. I have to be a hypocrite in front of them. I will pretend to listen to your story when I don't even care a single tiny bits of your story. Just hear them. Let their words come into the right ear, and come out from the left ear. Not forget to mention, better don't lie to some people! It will be the best if you don't lie to all of the people though. Just avoid those 'some people' (read:Sagittarius) like me. We will find out the truth eventually. No kidding. We are so persistent to know the truth. We are a great detective wanna be!
Sometimes, I think why should I have these kind of friends? May be God is testing me and my patience?
For now, I think that's all I can share. I will update if I meet another annoying personality.
