Sorry to join the pile-on, but typos do grate on me, and I don't think the word "tragedy" is spelled the same way twice through the entire thing. I strongly recommend spell-check before sending. I tend to assign lower credibility to something carelessly written, since I find myself thinking if the writer didn't care enough to check spelling, typing, grammar, and such, I probably shouldn't care enough to take it seriously.
[ETA: also caught "a few" run together as one word and a misspelling of "valuable". Good basic letter, but I'm sure I'm not the only reader who gets too distracted by spelling/typing errors to focus on content.]
