'I miss you'

I wonder what the phrase 'i miss you' means to people..Well,maybe everyone have different definition about what it means..

Here I wanna ask.Does missing someone means when you have not been seeing them for days or maybe weeks?Easy said,does missing someone means not seeing that someone's face?Because everytime I say I miss someone,they will think I meant that we have long not met..Is it really that?you miss someone because it has been so long since you last saw them.?

Some of my peeps may have got the phrase "i miss you' from me a day after we last met.Or maybe a few hours after we last met..But what do I truly mean when I say I miss them?Have you peeps ever thought of what I truly2 meant? Or maybe its just because you think that missing someone means not seeing their face?I shalln't expose what I mean by the phrase 'I miss you'..Maybe not ever..If you guys have got the time to spare to think about it,thank you so much..

Because when I say 'I miss you', it means more than just not seeing your faces..Because if I wanted to see your faces,I've got loads of your pictures with me that I can look at any time..
