What cultural faux pas should I try to avoid making in Peru?

"It is important to be respectful of local customs and traditions when visiting Peru. It is considered rude to point with your finger, so it is best to use an open hand when gesturing. It is also important to dress modestly, especially when visiting religious sites. It is also important to be aware of the local language and to avoid speaking English loudly in public. Additionally, it is important to be aware of the local customs regarding personal space and to avoid invading someone else's space. Finally, it is important to be respectful of the local culture and to avoid making jokes or comments that could be seen as offensive," remarked another expat in Peru.
