You would call a person who praises himself a lot a narcissist.
Bookeeper!
closed off
sado
a parrot
a procrastinator
A dairy farmer.
Hen hoarder
a person who tells proudly about himself is a boaster or a braggart.
The person who keeps your dog while you are on your holiday is called a sitter. Just like a baby sitter!
if you dont want them to call you, block their number
I would rather say that if the person talks about how intelligent they are then i for an adult call it conceded.
