Not to mention, always the first time you do any activity you feel that you are going to do it badly, but you have to be sure that everything will turn out well.
my dad taught me to vaccinate dogs and cows, but that is totally different than doing it with a human, the dogs raise the skin and inject in that space between leather and meat.
and the cows, insert the needle of blow very fast, because if do slowly it does not enter, and then add the other part of the syringe with the liquid or medicine to inject, that if I learned it,
just like your husband knew how to do it.
but in the case of a human is more stressfull, you're right, one feels that he's going to do major surgery, jaaaaa

but thank God everything went very well, and my friend was very happy only that he still does not feel courageous to inject himself, but we are sure he has to do it, in the future, my wife also injected at some previous moment and I never could by the nerves of damaging it I tried to inject her it and even the blood so she was sent me by a tube, and say me are you kidding me, you want to kill me, get out I do it by myself.
but today with my friend to see the emergency in which he was then there was nothing more to do effort and give the best so that he would not suffer so much.

Thank you very much for viewing and commenting on our information, we are in contact.
A big greeting and please enjoy the cottage or homestead where do you live, that can let you rest away from the voragine and bustle of the big city, and has the disadvantage of the wild animals that are coming to feed them, but I think it were ok.
best regard
