Ok, sorry it's a little late. First of all, the answer to the riddle I set last blog. Like I said, there are two possible solutions:
1) Mathematically. If you add two halves, then obviously get 1. But if you multiply them, you get a quarter (0.25).
2) The more clever solution: if you have the following scenario:
Jack and John are half-brothers with the same father. John also has a half-sister called Jane, whom he has the same mother as. Jack and Jane marry and have a son, James.
Now, John is James' half-uncle on his father's side, but also on his mothers side, make him his half-uncle twice, so to speak - two 'halves'. But it would be incorrect to say that this makes John James' 'whole' uncle. Therefore, in this case, two halves don't make a whole.
Anyway, hope you enjoyed that. Now for another song, as promised. This week: Sixpounder, by Children of Bodom.
