He tied the cross with silken thread , to hold the acorns , fifty nine . He placed it around his golden hair , and spent the evening with his flock . He prayed as each strayed sheep he found , and touched the acorns one by one . The evening late , the boy was weak , but counted on into the night . 
Question: What's a possible reason he spent the evening with his flock ?
Because he cares for them .
