I've never dated anyone and I never know for sure with things like this.
recently in my college I've met this guy (maybe 22 I think) through a male friend. he sits with us sometimes and talk, mostly to our common friend. I participate in the conversations and we have fun. though I've never showed disapproval unironically he's always trying to make sure he's not offending me and he always looks at me first whenever he makes a joke, but that's about it. I haven't thought much about it, since he usually pays more attention to our friend than me anyways.
yesterday, when lunch was almost over, I was hanging by myself and listening go music in the far end of the garden. he went all the way over, sat next to me, offered me candy and asked me about my classes, trying to strike conversation. I thought it was odd, specially since he only ever talks to me or my other female friends if we're with the guy friend. is it a sign of interest or something?
What Guys Said
When people are young, they are often more chaotic doing stuff just because. Particularly the more good looking people who've rarely received rejection, they often do stuff just because they have never had someone feel unhappy about them being there, so they can be quite random.
If though they are not as good looking and their general pattern of behaviour is to be reserved and then they do something like you describe, that's a sure sign of interest in you specifically. This is usually the rarer case though, because someone more shy and reserved is less likely to make a first show of interest unless they already felt maybe you had shown it them.
Depends on the context of the conversation
he started by offering me some candy and asked me if I wasn't going to class, I played it off and said something like "nah, don't wanna". he asked me about what classes I was having and offered me the candy again which I refused and said I didn't really know. then he asked if I was having classes with so and so next, I told him "not really sure, but yeah probably". I'm not sure where he was trying to get with that. I thought things were getting awkward and I got nervous so I just completely changed topics to something dumb we were discussing over lunch earlier and he went along with it. when the bell rang I got up to leave and asked if he was going to stay, he did so i just waved him a goodbye and went on my way.
Doesn’t sound like flirting… least not to my standards
