Answer:
they might actually not
Step-by-step explanation:
Girls tend to try to give guys signs that they want or need something, and it is not uncommon for guys to not understand. This could be because girls signs are too subtle, or the fact that guys tend to like to say exactly what they mean. Often it's a bit of both. What guys generally like is for the girl to come right out and tell him what she wants, because it's easier for them to know what the right thing for them to do is. If you aren't comfortable with doing that, try and make your signs more obvious.
