Translation of feeble in Spanish

I hope you you had a successful week in Dortmund. Because of the bad weather at the last moment I could not get on my flight to Dusseldorf and I have stayed home. I was afraid to fly.
I'm quite tired too by now. So, if it doesn't work just drop me an email and I'll see it first thing in the morning. I wanted to add new words to the dictionary however the other issues kept me more busy than I have imagined.
I sell clothes for children, women and men. I love my work. By the way: In Germany it is very cold, minus 15. We seem to be friends for years but have known each other just for two weeks.
