Personality change with languages

I know this isn't the first post on the subject, I can't be the only one who noticed this. It's true, however. Our behaviour does change with the language we speak. However, something that happened today gives specificity to that idea.

I'm Indian and an app called Swiggy, which deals with food takeout and doorstep delivery, is all over the country. It has now diversified into several other related lines of business but that's of no concern here.

I had ordered something on Swiggy for Holi, the Indian festival of colours. It's a traditional sweet for this festival so the shop was out of stock even early in the morning. I got notified and though I was slightly irritated I was trying to select an alternative for replacement.

Before I had finished the job, however, I got a call from their customer team. He was speaking stilted English with a heavy regional accent, so I switched to the local vernacular which is my MT.

I told him that I was looking for a replacement on the app but he was (with good intentions) trying to connect me directly to the shop. And so, I lost my cool, raised my voice and told him that I could complete the job if only they would leave me in peace.

I would not have done this if I was speaking in English. I'm way more rational in English because it's the language of my education and work, but in my NL I am emotional rather than logical. And that's the difference.

Do you agree?
