Unfortunately, there is also a downside to the opening of the windows. One is that the neighbors next door are smokers. But, they only smoke outside on their patio, which drifts into our back yard and through our open windows. I arrived home yesterday to find a bunch of candles lit throughout the house. Apparently, there was a lot of smoke coming in through the windows in the afternoon, and the candles were the only way to cover up the smell.
The other negative to open windows is the barking dogs in the neighborhood. I don't blame the poor pooches; I blame their owners. They put the dogs out and when they bark, if they acknowledge them at all, it is only to yell at them to be quiet. They don't want to deal with them, so they leave them outside and close up their own doors and windows. So now a chain reaction starts with all the dogs parking at each other.
Even though I really enjoy this time of year, and I love the freshness of the breeze coming in through the open windows, the negative elements make the arrival of Spring and and the open windows that come with it a mixed blessing.
