Today we tell about the expression “down to earth”．Down to earth means being open and honest．It is easy to deal with someone who is down to earth．Such people could be important members of society, but they do not consider themselves to be better than others who are less important．They do not let their importance “go to their heads.” Someone who lets something go to his head feels he is better than others．He has a “big head.”
A person who is filled with his own importance and pride is said to have “his nose in the air．”Often the person who has a big head and his nose in the air has no reason to feel better than others．
Americans use another expression that is similar in some ways to down to earth---“both feet on the ground.” Someone with both feet on the ground is a person with a good understanding of reality．She has what is called “common sense.” She does not allow her dreams to block her understanding of what is real．
The opposite kind of person is one who has his “head in the clouds.” Someone with his head in the clouds is a person whose mind is not on what is happening in real life．Such a person may be called a “daydreamen.”
The person who is down to earth usually has both feet on the ground．But the opposite is not always true．Someone with both feet on the ground may not be as open and easy to deal with as someone who is down to earth．
When we have both our feet firmly on the ground，and when we are down to earth，we do not have our noses in the air．We act honestly and openly to others．And our lives are like the ground below up—solid and strong．
