Ramblingrose22, thank you for your reply and pointing me in the direction of Wikipedia.
However, I am well aware where the tradition comes from and have absolutely no need to consult Wikipedia, which is considered unreliable anyway.
Times change and I know many people, who just see sending a card as a way of showing affection.
As I have said previously, I accept that we all have different interpretations and perceptions of situations and my motto is, "Live and let live". The world would be a pretty boring place if we didn't. I am certainly NOT assuming that I know what anyone else's mindset is. It is absolutely none of my business what others think, just as I would hope that others would accept what I think, without criticising or being patronising.
Furthermore, I indicated that I was glad that I had the mindset that saw sending a card as an affectionate gesture.
Also, I am well aware that by posting on GN, you leave yourself open to criticism and robust replies to one's posts. That's what makes threads interesting.
However, what has upset me is the use of words by posters (on what I assumed was a lighthearted thread) such as "creepy", "repugnant", "sexual", "inappropriate", "weird" when referring to the actions of people (like me), who send Valentine's cards to our children. The implication is, that our behaviour is in some way unsavoury.
I can assure you it certainly is not.
That is why I tend to post only on the games, Café and Soop's kitchen, everyone there is so supportive of each other.
Thank you for tainting what was an affectionate and wholly innocent gesture on my husband's part. I doubt if he will ever send another card.
Cherrytree and Kittycat, thank you for understanding what I meant by an affectionate gesture.
