If someone announces a win, buys a new car, or gets a new house, that is not an invitation for you to start begging them for money.
In fact, that should be the time for you to chill first. Do you even know how much money just left that person's account to achieve what they're celebrating?
Celebrate people without immediately asking them for money.
Stop begging! Announcing their wins is not an avenue for you to start begging them.
