Look, we all know that there is one thing that without fail will make us turn into a blubbering mess.

Everyone has something that can get the waterworks started instantly. However, there does tend to be certain individuals who just cannot seem to stop themselves, ever.

We don't know why, and sometimes it seems perhaps too forward or insensitive to ask.

Maybe they've been given some bad news, then it is probably best to leave it alone. Or maybe they are just too in touch with their feelings. Something will no doubt set them off at some point. We can’t imagine how you would cope when living with one such individual in close quarters.

Since he wrote the list, and then very kindly posted a picture on Twitter, people around the world have been sharing the snap.

"She's quite fantastically sweet like that. I don't think she ever thought the world would be worrying about why she randomly cries at everything.​"
