[header] How to not be annoying to your crush [title] Avoid being clingy. [step] Although you may want his attention, it's important to give him his space. If he feels that you respect him and his personal space, he may be more likely to interact with you. <sep> (A) [substeps] That said, if you catch him flirting with you, it may be helpful to drop hints that he's not interested. Try to keep conversations focused on something other than the discomfort that comes from talking about yourself with him. (B) Otherwise, he may view you as a needy person and stay away from you. For instance, if he doesn't respond to your text within five minutes, understand that he has his own life. (C) Do not talk to him about his ex-girlfriend, his building he likes, his family, or his pets. Doing so can just make you feel like a pest. (D) [title] Be nice to others when not around your crush. [step] People change their social roles and their relationships a bit, and you don't want to be around them physically until he shares these thoughts and feelings with you.
