How can I show a girl I like her without saying it?
give her a rose and just leave her to her thoughts? or send it with someone and just be around the corner to see her reaction
Do little attentions for her... Every girls Like that:)
You could do it through actions such as showing an interest in what she does, accompanying her to places she frequents or by asking her out. Asking her out should ideally come after you have been well acquainted.
Talk to her
Really you can't cause she might think your playing with her and don't like her just go up to her and tell her you like her!
