When you see him all day and you go home and miss him. You're in love. When he kisses you once and you need more. You're in love. When he hugs you and you never want him to let go. You're in love. And lastly, when you would do anything for him, anything to make him happy, anything to keep him safe, anything to keep him yours. You're truly, madly, deeply, in love and it is easily the best feeling you will ever feel. It's rare to find someone you truly love and truly care about so when you do find that someone, hold on to them, keep them close, do not let them love another.
