I've never seen lychees, only in pictures. Rambutan is a sweet fruit popular among everyone. There are many levels of sweetness though, from sour to very sweet. It's seasonal. Rambutan, Durian, Mangosteen, and Avocado bear fruit in the same season. Three days ago I picked a lot of mangosteens from the neighbour's tree. Nothing like sitting on a branch of the mangosteen tree and eating a fresh fruit.I had to look it up, LMS - interesting! Similar to lychee, which I've only had once, in Hawaii.
