Yes AL, you are right, sometimes even pensioners like myself need "guidance" with regard to the temperance of the language we use in our discussions with others and the need is even greater with those of tender years and inexperience.
I did, like you, accept the apology but pointed out that it would have been better had it been unprompted which is a fair enough point to make to someone of less mature years... guidance for the future do you see? As for the venting of my spleen remark, it was obviously (I thought) humorous.
Have a go at spammers? Are you joking? That really would be an exercise in futility, I'd rather do what I have done in that case, report them then put them on ignore.
