When you meet one of the bosses from your old (pre-transition) job in a restaurant and he stares you in the face with glassy eyes.... Not recognizing you, turning around and walking away.
When you meet this guy and he asks you whether you're aware there's a guy running around the same city who looks just like you. Told him I was my own cousin

When you don't get stares (EVER) in the bathrooms
When you're in a discussion with a friend about wanting children and she asks you whether you feel like getting getting pregnant within the next year or so
When you're having yet another heated gossip session about men...
-----------------------------------------------------------------------------------------------------------
AND, sadly, on the negative side
!!!!! [TRIGGER WARNING] !!!!!
-----------------------------------------------------------------------------------------------------------
When you're starting to get harassed by guys alone at night, walking the last 500 meters home
When you're at a party and the faintest look of yours crosses this bloodhound ->-bleeped-<-s' searching eyes, and he immediately comes sit next to you, putting his hand on your back and moving it towards your ass without asking
... When the same guy doesn't understand the word "NO" ... and tells you you're so nice and you shouldn't be so insecure
... When another guy (at another party) steers the conversation towards your boyfriend (always say you have one!)
... When that guy doesn't listen when you steer the discussion back to the previous topic instead, and goes sitting so close you can smell his breath (yuck)
... When you walk away, have conversation with a friend, and he finds you an hour later, as you're a bit drunk and about to go
... When the ->-bleeped-<- actually ignores your "NO" again, grabs you, wraps his arms around you and starts kissing your face and neck, saying you must be his because you're so beautiful...
