Just now was open house and it was quite tiring and sianxx esp with the teacher's two 5-6 yr old sons wrecking the booth... One kept destroying Yi Sheng's robot head and attach it with as many "red wings" as possible... Then Yi Sheng decided to screw off the whole head... Those two kids kept screwing whatever robos that they can find... But luckily they didn touch the catapult which Liang Hui kept playing with... Otherwise it would be "2 Mad Kids On The Loose" if they do know how to fire it... Hahas... In the end at 12+ then we were allowed to leave... phew... And to think of it, i didn even introduce RV to any parents... sighh... X_X
