Based on this twitter comment.

Pulling weeds is quite a step down from being shot at on the training ground. Right now I'll take it, though. Allows me to keep my head down and hide the colour in my cheeks. I don't need to see it to feel the red burning there.

The guys are rolling around laughing and I want to punch something. And all over a stupid tweet.

I know my family were worried about me when I enlisted. That they waited for news to hear how I was doing. And while sitting around a table writing letters was weird after being used to phone calls and texts, we all did it. I can't imagine making my first letter home something as meaningless as a random person's autograph. Neither can I imagine his parents finding it as funny as that tweet implied.

I said so, too. And the answer I got all but floored me.

What if it wasn't meaningless to him?
