Got a charger??

I had lent my mobile charger to a colleague one friday, who forgot to return it to me and thus I was left without a charger for the weekend. When my mobile started giving 'battery low' signals, I went to my next door neighbour's place in search of a charger.
Uncle opened the door, I told him that in case he used a Nokia set I would like to have the charger for a while. He said he wasn't aware of what set he used and immediately went in to get his mobile. After a minute's invetigation he said his was a 'Hutch' mobile, so his charger would be of no use to me.
Before I could say anything aunty came out and asked what the confusion was about. When uncle explained to her she too went in search of her mobile and after a carefull investigation she too expressed that her charger would also be of no use as it was an 'Airtel' mobile.
By that time I had seen that both used Nokia sets. So I asked uncle if I could take his 'Hutch' charger for a while and see if I could somehow manage with it. Uncle was only too happy to be of some help atleast. He got me his hutch charger and I hastily took leave.
Later when I informed him that his hutch charger worked fine with my nokia mobile, needless to say both uncle and aunty were awestruck with the advancement technology has made.
