Wedding haiku

Dear Haikusue:

I'm getting married in September and have budgeted fro a very small reception.  My fiance and I don't have large families so we are totally fine with something a little more low-key then usual, the problem is my coworkers ALL think they are going to be invited even the ones that I am not close to or don't like at all.  How to I gently let people know that our wedding is close friends and family only?

Signed,

Engaged in Emeryville

Dear Engaged:

Sacred commitment

not a public Barbeque

politely stand ground
