I do thumb love with my youngest daughter. xoxoxo. Txting is her form of communication. To my husband's blackberry I send ((hugs)). My son does cell and txt but won't do email. My oldest gets my love via email and cell. My mom? Landlines and email. My brother? emails but he only reads the first line on his treo.
Love is complicated. I'm excited for parent's weekend to give mother love in-person. ;) Live love is best. My latest oft-repeated phrase to my husband, "Have I told you today that I love you?"
I used to sign my personal letter closings (when I wrote them) -- Love, (me).
Here I just say Cheers and if I love ya, I'll link.
