Translation of Unsterblichkeit

I did not want to give them any money so they became more aggresive and began holding my hand and said 'please, please' all the time. Finally I decided to give them some money but could not find the wallet.
In addition, I want to inform you that I found a possibility to deliver a more Spanish lessons from Vocabulix. To my knowledge, the lessons are excellent and a great base for the Spanish training.
That is great. Thank you for the support (and for the compliment). Recommendations by universities are always very appreciated, as universities are usually more selective about external resources.
