<human>: I have known this girl for quite a while (3 years in fact) but never got to know her very well because of our age and grade difference. I knew her two older brothers who I am good friends with, this is how we first met and talked. Those conversations a few years ago were awkward (because of my own shyness back then), and through knowing her brothers I got to know her a little bit more over time (i.e. movie nights at there house, parties, etc.).

I haven't had a conversation with her in a year due to the aforementioned grade difference and her brothers are now at college. I do get to say 'hi' and 'how on you are' to her once in blue moon if we bump into each other in the hallways on the way to our classes. I feel as though it will be awkward to try to start a relationship after not having a real conversation in a while.

<bot>: I have known my crush for a while; I feel as though it would be awkward if I were to ask her on a date after not talking to her for a year.
