Alex is working on robot number three. Here is a list of things that this means:
* Vast quantities of time for Alex to spend in the garage, tinkering until his heart feels content.
* Vast quantities of unintelligible conversation directed from him to me, until my brain melts, and I can correctly pronounce potentiometer (though I'm not sure if I can spell it).
* Vast quantities of our little dollars flitting away into Ace Hardware's nut and bolt bucket until our wallets feel sad and alone.
* Vast quantities of nasty filed dust filling the air of our garage, clinging to Alex's clothing and hair and lungs until his wife imagines strange iron-lung diseases that he will be suffering from very soon.
