我想，只要是一位耕者，心田或许永远是播种的季节，也会永远守望着那一季之丰硕的。尽管他们眼前有飘零的叶子落下。季节总是无声的轮回，然而，季节里的旧事越发的清晰。总会想起刚刚刨出来的红薯，紫微微的散发着泥土的芳香。在那秋风刮起的田野，拔上几棵毛豆，掰下几穗玉米，挖出些许花生，在避风的地方用柴火熏烤，瞬间就会散发出醉人的清香。然后，跑到柿树下摘下几个红的发紫的柿子下肚，一顿真正的“野餐”就这样过去了。后来，入伍到空军，每每中秋刚过，在遥远的北疆，总会收到母亲亲手缝制的布鞋，这样的布鞋穿在脚上不捂脚。我穿着母亲做的布鞋，度过了一个又一个深秋，走过了一程又一程的路。母亲去了，那一双双曾经伴我远行的布鞋，一针针，一线线，却早已隽刻在我生命的过往里了。
