Freddie: Yesterday I went to the park with my nephew and saw so many obese children! So sad! :(
Kevin: they aren't even over-weight they are simply obese these days!
Harry: i didn't see a single obese child when we were children!
Freddie: i know. shocking!
Harry: why do you think that is?
Kevin: they get rubbish like junk food, sweets, fizzy drinks with loads of sugar etc
Freddie: but first of all they don't move! just sit there playing games!
Harry: i feel sorry for them! adults are responsible for it! 
Kevin: you're right
Freddie: this is our responsibility to teach children what's right and what's wrong
Freddie was sad to see so many obese children yesterday. Nowadays children have an unhealthy diet and they do not move much. Ultimately, the adults are responsible for this.
