Open House - Go or not go

I've received a few invitations for open house this week, but still thinking go or not go? people say, elok untuk mengeratkan silaturahim, open house by my straight friends I guess I am okay with it, but how about open house invited by PLU's. Erkkk...??? Byk bende lain nak di open jugak nnt kan! For now I still say NO, thank you. Why? Banyak reasons.
