When you don’t respect the rejection the first time you end up hurting yourself way more later on in life. Learn to fall back & do something better with your time.
When people have peacefully & respectfully shown you that they’re not interested in you or being around you it’s wise to respect that distance. Don’t hurt yourself out of pride & ego.
Don’t get emotional, angry or mad when they block you & you can’t speak to them no more. Especially if they made it clear they don’t wanna socialize.
