What's the deal here?

Some girl I met way back in January texts me asking for a favour. I don't want to deal with her bullshit request, so I ignore her.

5 days later, she calls me. I tell her to find me after the holidays. She gets snarky with me.

Blocked her number. Deleted her contact details. Moving on.

Another girl I'm working on texts me a few times on WhatsApp. She's boring as fuck to talk to. She's a single mom (which I read here is something to be avoided). I'm spending my time on hotter girls I met since then.

Texts me "what the fuck?"

Both are basically strangers whom I owe absolutely nothing. Yet they are offended I'm not paying them attention?

... What the fuck is their thought process here?
