That's why I have no crush

At seventh grade I used to have crush on Turkish boy he's not my classmate but I always saw him next to my bus or infront of the school gate, but I never talk to boys in my school, cuz I don't know I just don't feel comfortable, anyways  my best friend told me she have a crush when she showed the picture of her crush it was that boy so I didn't tell anyone I have a crush on him and forgot about him cuz why would I lose my friend for a boy who doesn't even know me? Anyways so the next time I had crush was two years ago, I had a crush on a boy I don't his nationality but he was two years older than me but he was nice to me and like he's cute so like he then confessed that he likes my older sister so yeah I said the same thing why would I lose my sister for a boy who doesn't share the same feelings so yeah I really have bad luck with crushs that's why I only have crush on celebrties, (forgot to add one time I had a crush on a boy and found out he's gay) but I'm still young for ts shi lemme focus on my grades better (I just wanted to share it I found it funny)
