Lack?

Lack is a perception of something that you wish you have that you do not... yet?

Lack is a feeling of loss that you should have something but you did not... 2nd chances?

Lack is a want that is not yet fulfilled... when?

Is lack real or is it something that you mind tells you to believe...really ?

On long bus rides, I love to just let the mind ponder... but I do know I miss you... too?
