I was reading Rebecca of Sunnybrook Farm, and I came across the phrase "April smile." I was unable to find a meaning of this phrase using Google, so I thought I'd ask here.
Here is a quote where the phrase is found:
"Give me some more examples of the subjunctive, Rebecca, and that will do for this afternoon," she said.
"If I had not loved mackerel I should not have been thirsty;" said Rebecca with an April smile, as she closed her grammar. "If thou hadst loved me truly thou wouldst not have stood me up in the corner. If Samuel had not loved wickedness he would not have followed me to the water pail."
— from Rebecca of Sunnybrook Farm by Kate Douglas Wiggin, 1903 edition, pages 61-62.
What exactly does the author mean by "April smile" in this context? And how does it differ from a regular smile — eg. said Rebecca with a smle, as she closed her grammar. —?
Summer should wander in your voice, and Spring Gleam in your gaze, And pure thoughts ripen in your heart that bring Calm Autumn days.
Yours should be winning ways that make Love live, And ne'er grow old, With ever something yet more sweet to give, Which you withhold.You should have generous hopes that can beguile Life's doubts and fears, And, ever waiting on your April smile, The gift of tears.
You should be close to us as earth and sea, And yet as far As Heaven itself. In sooth, I'd have you be Just what you are.' Alfred Austin
