That's right my friend, life is a daily learning, in the simplest and smallest things we always find that something that enriches us and makes us great, for example I have learned a lot reading your posts and that creative way you have to make your son learn but especially understand everything that happens around him and I was very surprised when you said you were an engineer because of your creativity I would have never imagined it, well you know they say that engineers are very square and sorry but I have met many like that and you showed that when you want to do things with love and dedication you get great and significant results.
