In spite of Sam feeling entirely awkward and weird around anyone with the Winchester name at the moment, he made it in point to drop by Mary's today to deliver her present. Since he's not really good at the whole Mother's Day thing, he kind of overcompensated and bought Mary something that he thought was trendy and cool, rather than...you know, something that one would normally give to their mother on the holiday. So, lo and behold, Mary Winchester now has an iPad! Good luck trying to figure out how to use it.
Also, at the end of the day around dinner time, Sam tried to drag Mary and Dean out for Thai food. Which I imagine would have been three times as awkward. Whoops?
