Medium

I went to Old Navy today, i like it cuz they have nice things for cheap, but everything nice comes in XXXL or XXXS, NOTHING! NOTHING! NOTHING NOTHING!!!!! comes in Medium!!!! NOTHING!!!!!!!! i found one shirt i REALLY liked and there was only one in the whole store and it was medium!!:) but it had a stain on it! , i hate being medium, small is too small, and large is too large, but medium is JUST right, but its never carried in anything nice:( oh well, i hope i look good with whatever i have. im nervous.
