Not everyone wants to be crop dusted by Chanel No. 5 and Dolce and Gabbana Light Blue when they get on the elevator. One or two spritzes are plenty, trust me.
When your friend moves into their new home, of course, you want to see it. However, wait until they offer to give you a tour instead of showing up and asking for one. They might not have cleaned a room or haven’t finished a model and would prefer to wait to show people until the home is in peak condition.
