My flash drive is my friend.
One of my best friends, actually, because my son already knows how to demand from me.
See, one of our players is this multi-player thingie that looks like a casette player. Aside from playing CDs, VCDs and DVDs, it also has a USB slot and plays what's on flash drives and thumb readers.
So if I want to entertain my son with pictures of him and his cousin, I just copy files on my flash drive and play. Hubs also updates the instructional videos there. Son is thus forever entertained.
But I know... I really shouldn't let him watch too much TV.
