Thank you milly - no, I won't yell at him for it won't achieve anything at all. He will simply zone me out. What happened isn't something that can be changed or bettered by yelling anyway. As far as punishment is concerned, as I first started this thread I was still feeling that *his action* ought to be punished. With valuable advice received here I have no wish to punish him now. I am glad I spoke about it and that I was able to look at it from other angles. An overreaction from my part was the last thing I wanted.
Thanks again milly.
