What is your opinion on public displays of grief?

In many countries like Italy whenever a person passes away their body is placed inside an open coffin for at least 24 hours so that people can pay their respects to said person and after that there is a long procession on the day of the funeral to the church and then to the place in which he/she will be buried. This whole ritual transforms and quickly becomes a public display of the grief people experience and for me personally it's not something I agree with because I feel it becomes a theatre act of who cries the most. No offence to those who believe in this ritual. I have always dealt with grief in private not wishing to be surrounded by people or have people see my pain. So what do you all think about this? If you have experienced grief how do you deal with it?
