some things we can say we've heard people say in our lives;
Our fav. cookie,it's so delicious being so bite-size,why dont we make them bigger next time we bake them,more to enjoy! Make them bigger please!
Wow,If you look at a house and you decide yes I could live in this house,but it could be bigger,get more room to keep furniture and a bigger kitchen to cook in,and and and more bedrooms for when company comes over,more room for the kids,and and bigger houses almost always come with 2-3 stall garages right? and and 2 stalls are better then just 1 stall right?!
More room right 
Let's get the bigger house..Wahoo!
If you a caffeine addict like myself,I prefer the 2 litter bottles of coke more then the 20oz bottles,cuz there's more to enjoy! Wahoo..lets get the big bottle,less time runnin back to the grocery store! Get the big bottle!
Most of this is because of human nature and society's beliefs
and why not,You only live once
