I HATE that some people refer to any connecting block as a Lego. THERE IS A BIG DIFFERENCE!!! People say, "Look at the Lego Halo!" and I say, "There's no such thing." They say, "Look!" and show me a MEGA-BLOK set. I can't stand them! If you locked me blindfolded in a room with a Lego and a MEGA-BLOCK, I could literally Smell the difference.
