[header] How to look appealing in front of your crush [title] Be cool. [step] Don't be loud or annoying, you want a good impression on the guy/girl. Don't look like an attention seeker (at/on anywhere e.g facebook, in person etc). 
If he/she asks you a question answer it and be polite. Ask open questions such as' how was your day? ' ' what are you doing tonight? ' and' what are you up to? '.
