Thursday is the kind of day that collects spoons. Not souvenir ones, just regular ones he steals from restaurants.
Wednesday is obnoxiously loud and has no concept of personal space.
Tuesday, on the other hand, is quiet. Serial killer "he was such a nice boy" kind of quiet.
Poor Monday is the Eeyore of the days, always being compared to its brother Friday and falling terribly short.
Saturday not only owns a beer can hat, but uses it regularly.
Sunday is prim and proper, a pearls and cardigan wearing WASP, until the sun goes down, then it's off to Tuesday's dungeon.
Friday is exceptionally chirpy, almost gratingly chirpy, but we put up with it because "Hey, it's Friday!"
