Honestly, I think the nicest thing you can do for people is to make your point quickly and keep it as short as possible.

For peers on collaborative issues:

Hello NJSpradin,

Hope you had an excellent weekend. I’d like to discuss the doohickey problem. I’m leaning towards XYZ, but I’d love to know your thoughts. Let me know when it’s most convenient to meet.

Thanks.

For peers or people that are not doing their job.

Hello NJSpradin,

As discussed, the delivery of the doohickey proposal is needed ASAP. Please make this your priority and let me know if there’s anything you need.

Thanks.
