Do guys really do this when they like someone?

So a while back, I was talking to an old guy friend of mine about a guy I liked and my friend told me that, often times, when a guy likes a girl, he will try and be somewhere where he can get a clear shot of her without anyone being in the way. Is that true? Obviously not all guys act the same way, but I just want to know if it’s true for some/most guys.
