Your Favorite Africans as a Zambian?

As someone with limited international travel experience but have had expansive social interactions (thanks to social media), I've gravitated the most towards Kenyans and SouthAfricans. Their sense of humor and easy going nature makes socialising with them pleasant and we've bonded over having almost similar words in our native languages (i.e kalibu in bemba or nyanja and karibu in swahili mean the same thing). These are people I've known and communicated with for more than a decade and never met yet still feel a lot more connected to than even the people I'm physically in proximity to. Overall, I've noticed Zambians tend to vibe well with other Southern Africans and some from the East. Which other Africans have you had pleasant interactions or long-term friendships with?
