Hi, I have a simple request, could you please speak in English more because there people from other places and countries watching too and we aren't able to understand your explanation. 😊

[@unknownff5254]

Where are you from?

[@Ihavebodiesinmybasement]

Exactly, that's what I thought. In the exam we won't write in hindi (ofc), so speaking more English would be better.
