So this expat-tourist girl (25) and I started talking yesterday and hit it off great, I asked her out for drinks she invited me to the beach she was at than and there alone nearby, I had stuff to do so I said I will keep in touch and tell her later, when I was done she was no longer responding (5pm)

Later on (10pm) she said she met some girls who invited her to go drink with them so she went but said we can arrange the next day (today) and now I told her I am free after 3pm, she said "ok I am on the same beach with my sister (around 18)

Wtf... should I go there and... do what, drag her away from her sister? entertain them?... I don't have a readily available single younger friend to entertain her sister hmm, I have 0 wish to play ball on the beach, I just wanna sit/lie down on something comfy and use kino touching which is my best skill to get somewhere, we also have common interests but the beach does not seem to be the place to discuss them imo... idk, I don't think I have a "beach game" except to flex and turn around so my abs can face the sun lol

However looking at her instagram pictures she only stays in one location for a couple of days hmm maybe she has plans later on

what would be the best course of action? she seems quite interested but a really unpredictable kind of girl
