So sorry to hear of your friend Steve's passing. He sounds like a wonderful man, and I grieve for his family and friends. I'm sure they understand you're not able to attend the service, but I know you're going to be there for them in the weeks and months and years to come. Grief, just like our post-surgery recoveries, doesn't operate on a time-table, and I'm sure you'll be there for them when they need a friend next week, next month, next year.
Meanwhile, I hope your training experience doesn't tire you out too much. Travel, training, wow. Take good care of yourself, OK?
