we did a surprise birthday party for my mil. When time came my husband and his sister took their mother with impression they were to take her out to dinner. They stopped at church and she wondered where I was and was told I had stopped ahead at the church to help with something there. When she started down steps we had everyone holler "Happy Birthday" we had asked everyone bring a dish and we had ordered a cake for her & all. She was really surprised and I think it all went well
