there's this guy at work and he's been trying to start up a conversation with me but it never works out cause i'm too shy and he's asked why i always give him three words but idk what to say hahaha i get pretty nervous and don't wan't to look like a fool.. i'm pretty insecure about my braces and it's hard for me to look at him without me looking like an idiot.. the other night at work he walked up to me and saw my name badge and told me that his name and my name was cute and he pulled out his phone, thinking he was going to ask for my number or whatever but my work friend caught his attention and i walked away in awe ahhahaha idk what to do... like i want to talk to him and maybe hang out i just don't know how to act like i'm interested and i don't want him to give up trying to talk to me 😞 
HELP PLEASE 🙏🏿
