Hi all, I've just taken up a junior teaching post (Teaching Fellow, so below Lecturer/junior professor, but it's post-doctoral), and as part of my job I'm convening one module, which involves practical classes. The practical classes and assisted (and in some cases led) by PhD students. As course convener I was thinking of inviting them to my home at the end of term for pizza and beer/wine as a thank you for their work on the module. Is that creepy and weird, or a nice way to show appreciation? It's a reasonably informal department but there doesn't seem to be much socialising generally, so I'm not sure whether it would be seen as inappropriate or uncomfortable here.
