I am really fond of that kind of picture. It shows the love between a brother and his sister. It recalls us to prove our love to the ones we love the most : relatives, beloved, friends, even in a platonic love. Making some warm cuddles doesn't mean you are weak or you wish to be engage with someone, it is just some few seconds of happiness, shared with an other human being. Let's hug ! You do not know about what tomorrow will be made.
