Where does a little boy go

Where does a little boy go after he leaves his carefree life
Where does a little boy go he's a young man a looking for a wife
Where does a young man go with a woman and a family that really cares
Where does a young man go he goes suddenly to some silver in his hair
Where does the silver hair go when this grownup man has settled in his ways
Where does the silver hair go it just turns right into yesterdays
Where did those yesterdays go they just seemed to disappear into the past
Where did those yesterdays go they turned into memories so very fast
Where does a memory go will it stay around to last and to enjoy
Where does a memory go there'll be memories as long as there's our little boys
Where does a little boy go
