Adjectives and adverbs (words that modify nouns and verbs [respectively]) need to be close to the word that they modify. If you put too many words between a word and its modifier, you might confuse the reader.
Incorrect: Standing in the rain, the drops mixed with the tears in his eyes.

Correct: He stood in the rain and the drops mixed with the tears in his eyes.
