Quoting I'm His Amy He's My Rory:" I have the same problem but I live on the 3rd floor and have a fatty to carry up. it sucks lol"
I live on the third floor too and I haven't had to climb so many stairs until I moved here about 6 months ago. That also sucks! My boyfriend just speeds up the stairs and I'm like half dying and also now that I am pregnant it makes my legs burn so bad!
