In one sentence, describe what the following article is about:

Many professors are required to hold office hours and a lot of students do not take advantage of them. Check your professor’s office hours, which they typically provide at the beginning of the semester. Go to their office hours regularly to get help with an assignment, talk about exam prep, or ask for help with a paper. Not only will they be impressed with your work ethic, but you’ll stick out. You won’t just be a face in the crowd of students, and you’ll form a bond.  Don't come to their office hours every week if you don't have anything to discuss. However, once you have developed the habit of seeing your professor during their office hours, you may come and just talk for a while about any other topic, not related with school. By this time, they will probably realize you are interested in them. Familiarity can lead to fondness. Simply getting in face time with your professor can lead to them developing feelings. Try to arrive to your classroom or lecture hall a few minutes early, and make it a point to greet your professor with a smile. Say hello, ask them how their day is going, discuss an aspect of the class, whatever! Just make time to talk to them one-on-one. They will appreciate your friendly and outgoing nature. Ask them with a question about class or about a homework assignment. Share your thoughts on an interesting discussion brought up during class. Send them a link to an article that you think they would find interesting. Just do anything to make yourself stand out, and find reasons to start a dialogue.   In your e-mails, stay professional, but a little bit playful. If you're sending an e-mail at night or during a day off, think of a witty way to justify this. If your professor uses smileys, include a winky face too. Every professor's boundaries in correspondence are different, and you have to figure out the best way of writing to your teacher. You don't want to be just another student who sends them boring e-mails every other day. Even if you want to talk to them every day, limit your correspondence unless it’s absolutely clear that your professor wants to speak that much as well. If you overdo it, you will be a nuisance.

Summary:
Go to office hours. Talk to them before and after class. Email them.
