Why do I have yet to hear, not only a single word of sincerity, but also at least a thank you?

i bought this girl, 7 things off her amazon wishlist, and it was not cheap to buy all 7. she's on onlyfans, and i follow her, but she's yet to not only say hi (other than to get me to buy a ppv) but, she hasn't even said thank you for the 7 things

two of them have already arrived at her place, and I still haven't heard a single thing

Yes, she's seen the messages, otherwise, she wouldn't have sent me the PPV's in private messages

+1 y
she finally replied

turns out she hadn't read them yet

nvm
