What are the similarities and differences of persuasive speeches and persuasive essays?

The similarity is that they are both trying to persuade a person or people. They both have the same structure and both should be written the same.

The difference is that an essay isn't something verbal unlike a speech. A speech requires you to connect with your audience. With an essay, the audience reads your tone by what you write down.  

Some cultural backgrounds have different superstitions or customs, this can play a part in how they decide things. superstitions are important to a culture for example, an asian culture has a superstition about women putting their purses on the ground their money will be gone, therefore people in that culture try everything they can to not let their purse touch the ground in fear of it being true. also like how we avoid walking under ladders in fear of bad luck. customs may also play a key role a custom also know as a tradition, is something people in the culture have been doing for generations as a quick example, if a family has a necklace that the family's mother passes it on to her daughter in so on it's a custom in that family.
