today is a busy day

 Last night ,one of my friends gave me a message : what will you do tomorrow? why won't you come to xi'an and have fun with them!

But I have class today , a experiment about southern bloting .All the work needs to be done takes long time ,and we can do nothing but waiting.so it is boring ,some of us sat around just chatted . but when the time comes that we need do the next step,it  became unorder,funly even if the first one has done his part already ,he have to wait until the last one have his part done!

It has been 5 hours before we can stop to have a break and feed ourselves!
