Invitation to team lunch for project I haven't contributed to
1
Here is the situation I work 'in' Team A, 5 of us. I occasionally interact with my team members for day-to-day work, but, there is zero work overlap. My work primarily involves Team B. Team A works closely with Team C. Team A + Team C are going out to lunch to celebrate their accomplishments, which I have no part in (apart from 2-3 times I helped debug) I haven't been officially invited for this yet. If I am (just because the entire team A is going), I want to be prepared with a response. Head says I should just join and go along with it, but, heart says should I politely excuse myself. I feel a bit awkward as I don't have any contributions to their project. Any ideas ?
