You have the option of praying in front of others or privately. Meditation is a common method of prayer in several faiths, such as Buddhism (or, sometimes, prayer is a standard form of meditation). In some cases, it is recommended that you not pray out loud because this would be considered interrupting your meditation, but this is not always the case. Many religions have teachings on how to conduct oneself while praying, most often in terms of being quiet and attentive. In many cases, listening prayers are preferred over spoken ones because not only does this allow others to pray without being heard by others, but it also allows the prayerto focus on God rather than other people. In general, people should feel free to pray in the presence of others as long as they are not being disrespectful or intrusive.
