Right, I don't think it's a problem honestly....I did it all the time when my kids were young...my daughter is Elsa and my son is George....so anytime I called them, my son became El-george and my daughter was Jer-elsa! When they were little they actually thought it was their names. pffft
I don't do it much anymore, although I am terrible at remembering names, period...never forget a face. I have photographic memory, so that helps...with some things. Just not recalling names correctly, I guess.
