Sounds kind of stupid but in my mind anyways kind of shows the difference between guys and gals. When I get an email from a lady who I have a good relationship with they will typically close with "hugs", "kisses" or the typical xoxo or something similar. Not criticizing I think it's a sweet gesture and I like the sentiment and playfulness behind it. Much better than youres truley or sincerely those sound like a formal letter Eleanor Roosevelt would have written. But for the life of me I can't come up with a male equivelant to that. Just think that would look pretty dorky from a guy. And guys tend to be less subtle anyway but you can't close a letter with "pinning you're feet behind you're ears, Case or "licking you're clit till you squirm in ecstasy" I typically use a generic "stay safe" or "hope to see you soon" . Any ideas hate to sound like Mr Rodgers when ending a message. And "until we meet again" just sounds like some fake ass crap from a Nick Sparks novel. Suggestions and while we are at it ladies what's the weirdest salutation you ever got?

is the hottest I have received  recently
Kind regards and Best Wishes and Thanks also suit m

would it be better if it said....."again soon"  at the end..?  

It leaves it to one's imagination.

Yes it do   !
