Only One Topping?!
Even after you have both moved out of your parents’ home, it’s possible that you will continue to rely on your older sibling for assistance if you are the younger of two siblings. This is especially likely if you are the younger of two siblings with an older sibling. On the other hand, this does not mean that the younger sibling ought to take advantage of the kindness shown by the older sibling.
However, the fact that they persisted in asking for something else even after they were informed that they would only be getting one exemplifies the sense of entitlement that is frequently associated with having a younger sibling. Even though the elder sibling explicitly said that he/she is short on paycheck, the younger one does not seem to care at all. What a unique sense of entitlement!
