Are mere words enough?

What are you gonna say when you are asked to comment about a friend you regard highly and respect deeply? Are mere words enough to cover the extreme guilt you feel when you can't even help him during his darkest moment. Words, no matter how they are filled with grandeur and poetry can't cover the fact that I didn't do my best to help him during his hardship. What else can I do apart from writing a comment for him and sounding upbeat during conversations with him? To put it simply in mere insignificant words it will go on like this...Jonathan is my pillar of strength during hardship and a figure to look up to on sunny days. An elder brother to have where you can joke, tease, share secrets and feel comfortable with his presence. Thanks for the memories...
