One of the cool things as your kids begin to grow up is that they begin using some of those cool toys you use, specially those that you remember fondly. Lego is one of those toys.
See how your kid play, and how you have grow up and are expecting your own playing time to be it is an interesting experience. I love the experience of really used your imagination, the idea that the block is more important than what the set can build, that the colors all match and the vehicles can do incredible things.
If you have the luxury of having a kid around sit and play Lego (or any other toy that will allow them to use their imagination) and remember what your imagination was able to see, dream and accomplished before you learned about fears, reality, bills and that thing people called “Real life”
