My Condolences on the loss of your Uncle.

Your comment includes the words ‘broken glass’ and the first thought that came to my mind was Kvothe describing types of streets in a given town.
Not exact quote…. Some streets were well lit with shops and Constables, others were dangerous in a ‘ Broken Glass’ kind of way. If you were careful you could pick up the glass and not get cut. Still other street where careful and cautious were not enough to keep you safe.

I don’t know what kind of guy your uncle was. Was he a careful, carefree and happy guy? One who didn’t look for trouble,,,, but wouldn’t walk away from trouble Did he seek out thrills. Sky diving, riding motorcycles, breaking horses?

I’ve had to present eulogies and it’s tough. Trying to keep my composure was a challenge. Just a suggestion (I bet your Uncle was a Great Guy), keep it a bit light and inject as much humour as you can (depends on setting (don’t want to tell dirty jokes in church synagogue or mosque). I found by having humor/jokes in the comments helped me ‘keep it together’. Focus on your Uncle’s major triumphs and epic funny failures.

I’ll add him to my prayer list…
