Who is to blame?

There are five things in a persons life which define him:
1. DNA
2. Social environment
3. The sun
4. The moon
5. Idiots around him

No. 5 is not included in No. 2. since I do not count idiots as part of the social environment - call me an idealist!!
But if I do not include the idiots in the social environment .... what is there left? Very little, very very little ...
