Can relate to the boxes !!!
Remember when I used to have to go into the bank to do some updates 20 years ago... would take my little daughter with me, get a box that paper would come in, cut out a 6 x 6" slot in it and set it upside down on the floor --- she would slide her legs under HER
'desk', so she could work like dad
worked out well for entertainment until I was at the console and heard the telltale "Pffffffttttt...." of a IBM mainframe FBA device powering down behind me and turned around to see her 'playing' with the "colored lights" (the blinking access and power buttons!!!!!)
All I could do was giggle, shutdown for the day, and go home to play with her !!
