One swallow doesnt make a Summer

Its absolutely perishing, snow, sleet, wind and rain. Its been a grey wet day with a gusty wind and a grey sky. Ive never known such a Wintery atmosphere in April. Thankfully the sheep are lambing slowly as the fields are too wet to turn them out to, they are best inside this kind of weather. It seems this Winter never ends, neither does the rain. Its got beyond a joke and its gone too far. If this is a result of global warming then we in the hills are going to get the sharp end of it first. Already the animals are turned out to grass a week later at least than when I left school. Summer is arriving later. Funnily I saw the first swallow roosting in a building tonight. I guess it will be regretting arriving just now, even though I have seen them a week earlier than this in the past.
