My dad gets really touchy with me..?

if u feel u can't discuss this w/him safely, try speak to a trustworthy older relative, friend or... if he keeps doing something that he knows is uncomfortable to u, he's not a caring person/trustworthy. maybe he's just awkward & self-absorbed, maybe worse. trust your intuitions--if u are cringing,he should be able to sense that &act different/better.
