I just celebrated a year where I work and I'm beginning to debate inviting co-workers. I know ettiquite says if I invite a few then I should invite them all ( I work in a hospital so it'd be an additial 20 people or so) The thing is, with the exception of about 3 girls, I don't talk to these people outside of the workplace. Nor can I tolerate how petty and "cliquey" these adults are. Is it wrong to just invite those 3 I'm closer to or do I not invite anyone? We're having a close family and friends reception so I guess I'm not sure how to answer the "am I invited" question. Thoughts?
