When they've actually clubbed me on the head is usually a good clue.
Give it time. If they really want to tell you something, they'll repeat it in all sorts of ways.
Another test would be to distance yourself from them (subtly) and see if they follow. Boys are sort of like puppies that way (assuming you are a straight girl. But this is true with everyone to a degree).
This right here.I am a flirtatious person, but I do so mostly in an innocent and friendly manner and so I tend to think others who flirt have the same intentions.
The only way I would know that someone's into me is when they actually tell me so explicitly, otherwise, it'll all fall into the friend zone.
...and I just realized how horrible that can be.
There are usually signs. Body language, an influx of compliments, a desire to be around you more... It's all encompassed in flirting.
Guess I've never had anyone hit on me
when they use a cheesy over used pickup line.
