dubstepped thank you for sharing this.I hope you and your wife can get the opportunity to do more such presentations like this at other schools of learning ,well done .
On a lighter side: At a TMS you would have got a G for presentation and delivery but I`m sorry to say your wife would have got a W for appearance simply because she wore slacks ,and then would have been taken into the backroom for a dressing down from the Elders.
Apart from that I loved it
