Nothing
I do it all the time. Some people just take notice of every little detail and they need sort out what they take in as well. I am not that blessed but I do notice a lot.
I take what I see and refocus the output to something constructive.
Seeing a need that another may let me know where I should focus my prayer for that person.
Lord, let that person find out what soap is used for.
Lord, let that person gain a vocabulary.
Lord, let that person find peace so they won't be so negative.
Lord....
Understanding why some people do things as they do helps me understand why they do what they do. The negative person with the low selfesteem in the meetings.... A positive reply that directs things in the right direct would work.
Yes John if that happens, you would be right but if we don't try we will never know. I think we can do it and with your help it should go ok.
By letting him know he can be an important part of the success, you would be motivating him and helping him lift his selfesteem...thus over time be removing his negativism.
