Do you eat Fish and Hot Cross buns on Good Friday?

It is a tradition among catholics not to eat red meat on Good Friday as a form of self sacrifice on this day. Fish is the preferred food. There are other form of sacrifices like other religion practice which is fasting abstinence. This does not mean fasting on food alone but on other favorite things you usually do as well. This is not compulsory but but most of us do it as a tradition and it is also a form of self cleansing and doing self sacrifice. This is in memory on how Jesus made more sacrifices and gave himself to us.

Maney people are tired of the troditions today,because we all want to have the free and comfortable life,don't want to be limited by others.I like fish very much and I think it's very good for our health.But can you tell me more about Good Fridy?
