a senior executive
One of the best sources for Startup investment: DAHEJ(DOWRY)
You won't believe my senior has a good corporate job with over 10 years of experience. But suddenly resigned just a few days after his wedding. We all thought maybe he got married and wants to spend his time with his wife, and decided to go to his place to give him a proper farewell. All of us got shocked after knowing that he left because his father-in-law gifted him a fat cash amount and a car in the name of "blessings." He’s using the money to fund his startup and the car for "business movement." I mean seriously? People are now using dowry as startup capital and walking around acting like CEOs, playing boss with someone else’s money. Bas, shaadi karo aur apne sapne chalu karo, courtesy sasural. I don't know feeling inspired? Or disgusted?
