I felt the urge to replace them with new trees from the same-store.
Why did you replace your old trees?
The salesman said the older ones were not real.
Natural trees always look better than fake ones. It's good than you got rid of them and planted new real ones.
I can barely tell the difference now.  The fake one looked fine.
I think you will come to appreciate and care about the difference in time. Honestly, I think having the natural trees will be more beneficial to the house.
