Repetition is the key. The sum of those small talks makes a friendship. If you’re nervous, practice your small talk in a mirror, but make sure you keep it up. Talking about the weekend you just had or the one you’re about to have is always an easy convo.

depending on your vibe, literally saying that could work

Take whatever I say with a grain of salt as I am an introvert and had few friends growing up. But I am old now so I have. um. perspectiv. Relationships. Even freindship ones. Are complicated. There is just a kind of flow. Some folks have a personailty that makes it come easier and some not so much. Im not sure its so great to try to be someones friend or such as opposed to just being nice and open with people. If you feel a bond with someone then you likely will lossen boundaries when opportunities come up. If they forgot their lunch or are hungry and you can offer them something and it does not put you out then sure do that. You might not with someone else simply because you have a good feeling with this one. It really does need to be an opportunity. You can’t just run them down and be like. You look hungry have a candybar. You need to just kinda notice if there is something where you can stretch yourself a bit and be able to do a nicety. Remember. Grain of salt. Im kinda a dork (this is a term old people use)

You go to her and say: «  hey you look friendly «… and you take it from there.
