A wry remark intended to make light of da fact dat a period of da winter has been very rainy.
Jokingly telling fellow adults dat, "At least we don't hafta shovel liquid water" may indeed make them feel better about a drearily-wet portion of da end/beginning-of-year season, but small children may not be over impressed or cheered by said statement, since they would much prefer to have snow dat dey could go out and play in.
