It was a dark Spring day. The clouds were firmly ensconced, and leaving the Firmins feeling like they were stuck under an enormous duvet. Sue felt it especially, since for a while now she'd been underneath her own dark clouds.
Every action they took felt particularly difficult, whether it was a cordial greeting to the person at the check out, or dodging the latest onslaught of brolly-wielding maniacs bearing down on the street. Time would tell before one of them would break, and it was anyone's bet whether it would come before a break in the weather or not.
