Your age will be relevant, though. If, for example, you are 13 and he is 17, then he is too old for you at present and is probably just being friendly. However, if you are 18 and he is 20, then there could be hope of a young romance, while, if you are 25 and he is 30, then you should really start chatting and see where this is going.
If you mean 'school' as in 'school rather than college', then you are probably both teenagers, but the age thing will still be relevant and so will being careful.
Take care
