Da manche eine Bio toll finden, dann schreib ich mal hin was mir Spontan einfällt, da eigentlich über mich nix tolles zu schreiben gibt^^

Fahre gern E-Scooter (Super um Fix von A nach B zu kommen) Interessiere mich auch für EBikes und Lastenräder.

Finde Autos nicht doof, nur die dummen Autofahrer die da meist am Steuer sind.

Sonst finde ich vieles Interessant, merkt man meist am Kommi drunter :)

Mehr fällt mir gerade nicht ein was hier so stehen könnte
