21 + 21 + X = 52 ...You're getting close!
And 29 January is my youngest son Haroun's birthday, too! (he's 13 now). He got a massive chocolate 1/18 scale 356 C !!! Haroun has, after discussion with his family, decided he would eat the chocolate: it is just about impossible to keep the thing below the max. 20° C
(that's 58° F) to keep it from sagging, and we wouldn't want to do that to a Porsche, now would we!!!
Young Mr. Rufblackbird: joyeux anniversaire! gelukkige verjaardag! glückligem gebürtstag! May the force be with you (to withstand the rest!)
