Words are powerful in and of themselves. If you take one simple word and put it into different context, it changes the whole meaning. Perhaps this is what makes the English language so complex.
Consider this:
'I love chocolate chip cookies.'
'I love the smell of buring leaves.'
And then, hear in your minds ear,
'I love you'
uttered from the soft, sweet lips of your child or your lover.
The emotion behind that word changes dramatically, and pushes your heart to overflowing. The previous two statements.....not so much!
Words can endear, encourage and enflame. They can sooth or smother or smolder your emotions.
I am much more articulate when I write than when I speak. Writing allows me to edit the words I think prior to hitting the send button to my lips. I am certain I would have more friends had I been able to measure each word before running my flapping lips!
So, as in all things of this life, choose wisely. Words left unspoken are sometimes the best. But words uttered in sincerity and perfectly chosen are not easily forgotten.
