"I notice that whenever a native speaker of English describes something with an adjective then the contrary adjective would follow, and it will appear in the comparative form. Take 'small' for example: "This car is small for me. I need a bigger one.", "This shirt is small. I can't put it on. I need a larger one." Can't we just say "I need a big/ large one"? Looking forward to your reply."
