should we tell or ask them 2 stop........

using our idea and if they know that they want 2 use it they should the only good one not the thing we say or tallk about,and if at all use the bad one then we will sue them for that because it was ours,

for example I was the one who said that I would love 2 see Milind making food for Prachi one day witch he did(the good old days)but I never said anything because that was really good and very nice to see and now that they r about 2 use the bad thing that we have said we will sue them for that
