Nobody knows the value of what they have

I am Egyptian and my family is living in Egypt till now, but I am live and working in another country now, when I was lived in Egypt I was out of my house all the time, I came home late just to sleep, sometimes I didn't see my family for 2 or 3 days because they were sleeping when i came home, it was a normal for me, I didn't feel anything strange.

I've been abroad for almost 2 years, and i missed my family so much, I miss sitting with them, talking with them, saying some jokes & laughing, I miss everything with my family.
 

I realize now I didn't have this feeling when I lived with them, and I ask myself, why don't people don't the value of what they have until they lose it? Do we have to lose something to know its value?

I hope you see your family again soon.
