Heyy guys, as i've mentioned before, my generic direct opener would be something like "i just noticed you and i thought u were really cute so i had to come and say hi"
now how would i follow it up in this sorta scenario?

Me: Hey hru?
HB: ntb thx, urself?
Me: good thanks, i cant stay long cos my spaceship (lol i jk - i mean bus) will come any second, but i just noticed you and i thought..blah blah, u know the rest.
HB: Gee thanks *gigglezzzzzz*
Me: ......lovely weather eyy sexy? LOL

Wuld i just continue with some normal conversation, totally irrelevant to the opener? or what would be good to follow up with?
Maybe a gambit? or a game? or a DHV story? ideas are now coming to me haha but i still want some advice too from you guys

It's up to you to calibrate.

If in doubt, plow through and continue to escalate. Worst case scenario is that you learn how to calibrate a social situation better.

By calibrate, you mean to assess the situation and see what would be appropriate?

You're 100% correct. That's exactly what I meant.
