I dont get it why people say this!

Hello everybody, I am a add'er
And yes I am calm.
To make it short, i just got a new job.
I feel very comfertable at there, and also with the people working there.
I made some new friends and stuff, and everybody who i meet I have a pleasant conversation with.
But later on I go to give my paycheck to the people who helped me to get the job.
And one of my chefs are there, saying I am too calm and I dont have team spirit.
Which I dont understand. In the mean time everybody is laughing at me like i am some shy animal. Which I am not, i was just standing there calm(duo my pills). They were all staring at me, like I am so cute shy thing or something. In my mind I was like what shut up ?, whats wrong with u guys(Sorry for the cursing). I am just giving my paycheck away. I didnt feel shy at all :S not blushed or anything. At the end I felt just akward, and walked akward and confused away.

Is my self-protait so wrong? I mean I made new friends, had lots of laughs with them. I feel very social, and helping.I did not talk much to my chef, because hes my chef. I mean did he not even ask my colleges how i am. Or do really have this shy body langauge?
And whats so wrong about being calm? Its not like I am a anti-social or something.
Man this makes me so angry.
edit: In comparison with my colleges I dont act different at all. Two of my friends also dont say a thing to chefs. And they arent stereotyped as a calm person.
Really this makes me wonder, I have a very symphatic face. And sometimes I have the feeling that people think I need to be SUPER social and nice and SUPER outgoing. But I am just being myself, and I am not a bad/akward/anti-social etc. person at all! If I say myself, I did a awesome job at my new job. Only made one mistake in one week.
I am so angry atm :S
