He seems nice enough and we're quite a small team so everyone knows each other and all our desks are placed next to each other too.
There is an empty desk next to me (as of about 2 weeks as someone left) and he keeps coming and sitting at the desk but not making conversation. I have every time started a conversation and kept it going but I'm getting a little tired of it now.
I know what its like to be new so I feel bad, but even when I was new I put the effort in to talk to people, especially if I'd gone out of my way to sit next to them.
