Are guys who are inexperienced in dating/relationships typically act weird when they like someone?

We have a bit of history together where he used to express some interest and now we share two classes together. In the past, he'd also sometimes be so in his own world (he's known to be aloof) that he wouldn't notice me around. Anyway, in one class, he seems to be expressing interest by sneaking glances etc when he can and more importantly, co-incidentally bumping into me or standing really near me and stuff as we wait for lifts etc.

But during the other class later in the week, I hardly see any sign of interest, no trying to stand near or interact/ no sneaky staring whatsoever. He's been single since forever though..

I'm thinking, person is the same, situation is different, they act differently.. why?
