What to think about it??

[charlize]

A person make an app and sounds like this his " lecture ":
Hi, can I make an app with you this evening in couple hours time?
Me: yes, ok, will you please confirm bla bla bla
Him: yes, but actually can I come in 30 minutes time as I'm close by
Me: ok ....

He arrived as we agreed, he walk in and introduce himself...and afterwords he apologies as he can't stay as he had a phone call to pick up his brother from somewhere and if he can come back in 1:30 min
Me, to be nice and polite I said if I can be available for sure
Walking to the door he asked me if I'm on my own and I didn't replayed
After 2 hours he text to invite me for a drink as he stay in a hotel close by me for the night

Well, for sure I ignored him but I can't understand those kind of people ??? This is what I can't understand

What was his intention??
Guys do you know??
