I realise it's off-topic (and I am somewhat cranky), but it's not the level of the explanation that is the problem - it's the way it seems to be addressed to a 7 year old ("He's smart!", "It's amazing").
As an adult, I personally would prefer if you explained something to me and let me be the judge of how smart and amazing everybody is.
