Briefly explain four cultural views that affect relationships?

There are even more examples, but here are four:

1. Miscommunication, especially if he/she are second language speakers, this can cause a lot of problems.

2. Religion. Just imagine a Christian dating a Muslim. If they are both religious, a lot of fights could arise from this.

3. How you express yourself. In your culture, something might be more acceptable.

4. Food. The food you eat vs the food that is eaten in a different culture, that you might not approve of at all
