Oh dear, @vm2904! I'm really sorry that you never got a chance to see the dolphin show, despite having been to Durban several times and spending years in South Africa. Believe me, it happens. I have lived in Belgrade for years now, but there are some tourist centres that I haven't been to. Yes, there is no gainsaying the fact that dolphins are lovely and intelligent like you've rightly stated. Your upvote is highly appreciated. Thanks for stopping by and keep the steem fire burning!
