I'm 5'5, and like /u/SirKolbath always says, embrace it. When someone makes a remark about my height, I usually just chuckle or laugh it off, it doesn't get to me anymore. But I'm kinda dry when it comes down to responses. I usually pull off the "Yeah must be tough for the little guys. I'm 6'2 though. Tall guys like me have things pretty good." (thanks /u/throwawaydegar) and it usually gets quite a few laughs.
Would appreciate some more responses to add to my arsenal. Thanks!
