I call him "mango" 'cause his name's Thando, so mango just goes very nicely withit! :) and I'm "Banana" (we like the fruit thing i guess!:D )
Sumtimes also "bubu", its jus sweet! Or "l÷ckchen" (= german-->little curl) cuz his afro-curls are so cool..^^
and i call him papa and sumtimes he calls me "mum" (but rather when he feels overprotected heheh..)
