Who can you see in this picture? A young lady? Or an old lady? Or can you see both?

I find it really interesting, cos I could only see the young one, until my dad pointed out the old one for me.

This is to say, 2 people may have different perspectives on the same topic or a particular picture or work, but that does not mean that only 1 is right. Sometimes, both perspectives can be right, even with 2 parties cannot agree with each other.

Cool isn't it? I'm SO gonna read this bk~
