We were given a topic ( renewable v/s non renewable energy) , two minutes were given for thinking. .. everyone started racing .. i wanted to settle down and speak after one or two people are done.. and tried not to rush ... But everyone started talking simultaneously.. everytime I tried to speak someone else started ..

So one or two times i interrupted and said.." our voices are overlapping , lets just speak one at a time"..it worked for some time but ultimately that race continued so i also spoke a Little bit in the favour of renewable ( overlapping initially ,, but later on he/she stopped) .. that's it

1. Dont be rude 

2. Mind that its a GD and not a debate

3. Be respectful and humble

4. Give others a chance to speak if you think someone is not able to .. ( by calling out their names..if you remember..
