Doeset it means if someone have eye contact eith yopu they like you?

No it means you are blocking something they are trying to look at and are just in the way. Unless of course, they continue to hold the eye contact for longer then a few seconds...it is a way of letting you know they find you physically appealling. They might be to timid or shy to introduce themselves so it might be a good time for you to take the lead and start up a conversation. Or if you are too timid then simply hold they eye contact and smile before breaking it, this little gesture might give them the confidence to take the next step. Good luck!
