A little background: I am a software engineer for one of the international corporations, and a new hire at that. Recently, some "higher ups" came to visit our site, and I was invited both personally and through electronic communication to basically all the meetings and evening lunches with them.
Now, they are really way above my level (it's basically CTO, CIO and global IT director of our company), so they are probably bosses of my boss' boss etc.
I am feeling "out of place" on those meetings, since being a recent hire I cannot really input anything of use (and most topics don't even concern me, anyway), and as for evening going out, I feel incredibly stressed, overanalzying everything as to not appear rude or saying something out of line.
On the other hand, I feel like declining those kind of invitations is a no-go.
There's 3 more days scheduled and I already feel burnt out by this. Is there any polite way I can cancel such meetings? I would not like to make false stories, like my mother is sick, if it can be avoided.
