If you tell your neighbor that you will build a wall along your property line, it is started and built the following day, in the next week, in the next month?  I bet not...planning, finding the right material, the right contractor, the right surveyor, the funding, etc., etc.  takes time.  oO you riding on Aladdin's carpet dreaming you can do it within hours after you told your neighbor of your planned action.

Stop pukeing...or maybe you ate some spoiled poke.
