Sorry.. Rant

Am I just being over sensitive? My inlaws called and asked what my son and I wanted from McDonald's (they claimed they didn't have my sweet chili wrap anymore when I know they do) so I said a fish Sandwhich and I heard my father in law in the background say does she want fries or just the Sandwhich... And she shook her head no.. Like I did want the fries... Does she think I am fat or why did she silently shake her head no and not ask me? ! I woulda just made something at home!! Ugh!! I could just be irritated because they moved in with us about 2 weeks ago and I feel like they are invading my space!!
