Damn you stacking cups

it's being a pretty difficult afternoon at the moment, Eve has found stacking cups in nannies toy box!
I had no idea these cups were here, now we are in a never ending flow of tears and tantrums!
she is currently trying to stack them up, when she can't do it (has the sizing the wrong way) she was cry A LOT bring the cups to me still in tears, I have to put the cups back together and she will run off, sit down and and take the cups apart, which again ends in tears, she brings the cups back to me, i put them together, she runs off she takes apart she cries she brings then back and we can see where this is going, this is when the day gets hard, do i carry on, letting her get wound up and upset? do i take them away again causing upset? do i superglue these cups together? but then no that would cause upset because she can't take them apart!

oh god I wish we could understand eachother!

actually I also wish she never found those damn stacking cups, those silly stacking bastards
