If there is a good picture of you and your friend clicked, majority posts it on Instagram with captions of love.
While that all may be true, real love for our loved ones is when we take a printout of that picture, get it framed, write all those captions in our own handwriting and gift it to our loved ones without any occasion.
You do not need social media to prove you care. You just need to be filled with love.
Try it out once, the feeling you will feel is going to be much beyond filling up an empty hole that social media attempts to.
