He probably likes you!
however
I think you should see what kind of person he is first.
If he is always glib with girls,
Then you can make up your mind not to trust him!
Then,
You used to sit at the same table,
It may also be related to "too buddies"
So it's natural for him to joke.
I don't think what you said mentioned your feelings at all.
Do you like him?
Or do you just treat him like a brother and sister?
You must first distinguish your feelings.
If he feels good,
Then give him the scarf,
Maybe that's what he meant.
If you don't like him,
Then forget it.
Finally, it is not good to avoid misunderstanding and embarrassment.
Although you promised to call him,
But you can make up a beautiful lie
For example, you can't play in the middle.
Or simply buy him one that is not wool.
