I mean, really? At first sight, this question sounds really immature, and you can’t really connect it with him being genuinely interested in you.
But, if you look at it from a different perspective, you will see things more clearly.
If a guy asks you this question, he’s subconsciously trying to learn about your personality type.
So, if you answer that you would grab your laptop first over some other thing, he will instantly classify you into a certain category, and he will be glad that he learned something new about you.
But, don’t worry that your answer will be wrong. The best bet is to just answer honestly and not think too much about it.
