Sentience in a seed-pod

Last night I went out to a club called the Orchardbank. While I was there someone set off a can of mace. I consulted with my lawyer this morning:

Geoff: I was in a club last night and someone set off a can of mace. It was mildly unpleasant. Can I sue?
Counsel: Dunno. Were you injured?
Geoff: I coughed and my eyes watered. Emotionally I was devastated.
Counsel: Wuss.
Geoff: Yes, but am I about to be a rich wuss?
Counsel: No, you're not about to be a rich wuss.
Geoff: Ok, ok - how about this: due to the mace trauma I lost my keys.
Counsel: And?
Geoff: Well, now I'm out a set of keys! I should sue.
Counsel: It would cost a lot more than the set of keys to sue...
Geoff: But I couldn't get into my house for hours.
Counsel: Did you suffer any financial loss?
Geoff: I could have caught chingcough while I was out in the cold.
Counsel: Chingcough?
Geoff: It's what my mom said I would catch if I walked around barefoot on cold tiles.
Counsel: But you didn't catch it right? So no medical bills?
Geoff: Technically no.
Counsel: So stop whinging...
Geoff: But people can't just go setting off mace with impunity! I demand punity!
Counsel: Complain to the club owner then - maybe you will score free drinks or something.
Geoff: Ok, going for lunch. Laters.
Counsel: Cheers dude.
