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

"It is important to be respectful of local customs and traditions when visiting Botswana. 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, as revealing clothing is considered inappropriate. Additionally, it is important to be aware of the local language and to avoid speaking loudly or using offensive language. Finally, it is important to be respectful of local religious beliefs and to avoid discussing sensitive topics such as politics," mentioned another expat when asked about moving to Botswana.
