You’ll actually know. They’ll take the time to talk to you and be with you. They’ll love you truly and unconditionally even with all your flaws. They’ll never give up on you through thick and thin and will fight for you until the very end. When you’re having a really crappy day, they’ll do anything just to make you smile. If someone really loves you, they’ll do all this and more. Cherish them and never take them for granted.
One thing that people should have nowadays. The feeling of being satisfied and happy with just one partner. Every person should learn this word and they can also learn to be happy.
