Many Slytherins feel very anxious when a person doesn’t respond to their message/messages. Slytherins often think that they did something wrong or the person now hates them if they don’t respond to “How are you” or another common message, after ten minutes. The Slytherin will often times over think or overanalyze the message that the Slytherin sent till the person messages back two minutes later. Then the Slytherin realises the person loves them and the cycle continues.
Slytherins often times are very sarcastic and say a lot of crude jokes around their friends. But when a significant other comes along, they often times act cute and innocent around them. The Slytherins friends are seeing right through them of course but just stand back and smirk
