Whenever I don't like someone that chats me I don't say anything until he/she logs out then I go offline in chat when he/she goes offline and when he/she asks me the next day why I didn't reply I say my internet connections f*cked up
I'm not even joking all my convos go like "hi... r u hot." then whenever they answer i say "do you like christina aguilera and madonna??" and if they answer no, i stop the convo right there.
