Subject：Just a suggestion
Dear Tom，
You did a great job with your presentation yesterday. Your visuals were especially effective；however, I would like to make one suggestion.A few of your jokes were inappropriate to your audience.Though seemingly funny, off-color humor can quickly alienate people.I would eliminate that kind of humor when addressing a business gathering.There are enough“clean”jokes left to spice up a presentation that do not risk offending your audience.
Hope you don't mind some friendly advice.
Yours，
Richard Wu
亲爱的汤姆：
你昨天的演示报告做得很好。你的视像资料非常有效果，但是，我想提一点儿建议，你有几处笑料做得不太适合听众。虽然听起来很好笑，但是庸俗的玩笑很快就会使人反感。当我在商务聚会的场合讲话时，我是不会采用这种幽默方式的。除去这几处，你报告中其余的那些“净口”笑料也足够给演示报告增添趣味，而且不会冒得罪听众的风险。
希望你不介意这些善意的忠告。
