Smuggling

I have been in the community for over a month now. One of my fellow newgrads who I hung around with for most of the year said that I have changed abit, and other colleagues at work think that I have too. How? Well... I have been rejecting offers to go out with them on parties and I don't chat with them as much, basically saying that I have become somewhat smug.

I don't have much to say to this unfortunately. I am there to work, not to socialise or have fun after work.
