Do you use code words to let someone down gently?

HOAAH
This girl said,"can you give me your address? i had a card for you but i just forgot to send it. Sorry!!" Then i gave her my address and asked for hers and she just ignored me. Is that code for i don't think you are friend worthy. Stop texting me like i have something for you. I don't.

Like one time this guy i was going to hire to do something said, sorry i can't come i have a dinner party. Then i asked if he could come another time. He just ignored me and never responded. Does the word, "sorry" actually mean that they don't want to help and to stop bothering them?

I deleted and blocked his number and called another company to do the job which i paid a ton of money for.

I might delete that girl's number and block her too. I think they were trying to be polite and tell me that i annoy them and to leave them alone. Am i right?

By the way, they both proclaim to be devote Christians.
