Sentient Slug

It's disgusting to admit but since we got back off holiday we've been terrorised by a slug.

Before we went we found a slug on the lounge rug. Nasty stuff, but we deduced it had come from the chopped wood we had put in the fireplace. We killed it.

When we got back from holiday we found more trails. Bastard! We checked everywhere .. no sign. Maybe they were old trails.

One morning we found new trails, the most obvious snaking through the middle of Claire's sandals. Nice. We took the lounge apart and removed all the wood from the fireplace; must have been in there then.

Nothing for a few days. Then, this morning Claire found MORE trails but still no slug!

WHAT'S GOING ON? Is this slug AVOIDING US?!

It's like it waits for us to go to bed - or leave for work - and then PARTYS ON DOWN!

I just don't get it. It's not even like the trails lead anywhere, they just randomly cross each other and fade away.

Maybe it's an invisible slug? Maybe it's shy? Maybe it just knows what we're like?

It. Will. Die.
