Why is saying I love you so hard? With certain people it's effortless, with others it's the complete opposite. The words bounce around in your head...when should you say it, how, following what other words could you squeeze it in...somehow those 8 letters can be felt in the pit of your stomach as they trek up towards your mouth.
You brush pass the difficulty to say it anyway, because it's important to you that they know. I mean, they have to know! Who doesn't want to know that they're loved? What if they never see you again, & you them?...
...but, maybe that's it.
Maybe the words can sound too much like 'goodbye'.
