Is this normal?

Ok so a client reached out to watch their dog and told me no the first time because of location. Three days later I receive the same message stating I'm the closest to them. Now they are also a sitter and their profile avilability is open for the dates they want me to watch their own pet, is that normal? They also didn't agree to meet and greet and changed their dates the second time they messaged me. Idk if I'm being paranoid but this would be my first client so need some advice
