Many thanks. He has now taken a post in another office and I have tried emialing him and speaking to him but have not got much of a response from him. I also gave him my personal number as I did not have a work one when I started, we were working on a mutual project. He only answers the odd email and never got back to me about any work questions. People never cease to amaze me. You want to add anything let me know. many thanks, caroline.
I would talk too him about him taken post at another office that is a good way to start a conversation in an e-mail. It's a way for him to respond on whether he likes it there or not in his new office. You also could ask him how he is doing in general. You want to get him to talk more in his e-mails. He might not know what to say so you need to give him something to respond too. Some times people do not know what to say back because they do nt know how to respond.
He might not want to talk about work, he might just want to talk about life in general.
I would e-mail him and just try to get a conversation going.
