Shelby,
luke 10:1-7
Look at the context:
10 After these things the Lord designated seventy others and sent them forth by twos in advance of him into every city and place to which he himself was going to come... 4 Do not carry a purse, nor a food pouch, nor sandals, and do not embrace anybody in greeting along the road. 5 Wherever YOU enter into a house say first, 'May this house have peace.' 6 And if a friend of peace is there, YOUR peace will rest upon him. But if there is not, it will turn back to YOU. 7 So stay in that house, eating and drinking the things they provide, for the worker is worthy of his wages. Do not be transferring from house to house.
This was a special occasion not like here on the internet.
If we aply it like you do, it would mean that the disciple would be saying "may you have peace" every time spoke after being quiet for a while.
NO WAY SISTER!
