Trying to buy a new scale

I made it up to a store to finally get my own scale again. I was at bed bath and beyond trying to pick out a new scale. I wanted something simple but the 2 old fashion wheel spinning type scales I had in mind kept getting stuck in strange places. I stepped on the first digital scale which had me at 116.4 pounds, the next one was 121 pounds, then 118 pounds, and then one just kept showing me a backwards E. I hit the point of confusion along with thinking that all these scales seemed to be 5 to 10 pounds more then I think they should be. The weights seemed great to me but I did not believe them and there were so many different numbers for the same me. I ended up not buying any of scales not knowing which one to trust and just left the store. On the way home I did realize that I am wearing a heavy winter coat, and have my shoes on so maybe the numbers weren’t as wrong as I thought. I think next time I will go weigh myself on my parents scale and then go weigh myself on the scales again to see which ones match the one that I have been using. That seems to make the most sense, or I can just say screw it and go up to the store when ever I want get on a scale. I can have a selection of what my weight can be…
