What is twitter all about?

WHY IS GOOGLE BEING MORALISTIC OR A PARENT?

This is so annoying..at night if you want to send a mail from google, it makes you do an algebra sum and ask you if you should send that mail out...why is google being so moralistic...what is it trying to prove from that? 

I dont want to be told what I should do or not..atleast while sending emails..I thought google knew it better that people dont want to be oreached all the time!!

Please Stop IT Google!!! this is annoying!!
