Im pretty good at assertiveness at home, and pretty good at it outside at times, but in front of other people (peoplethat i think i want to maintain a longterm friendship with -not necessarily this guy- but others whether its a girl or guy, with THOSE people I suck at assertivenss.

Any ideas how to get over that, and why its the case that i'm assertive but when its people that I care what they think about me, i freeze??
