Hello, Mawmaw?

This is the absolute most cutest thing I have seen in a while! Nicholas got two round objects and taped them together and made a telephone and then all of a sudden he looked at daddy and said "want to call Mawmaw? " within a minute he went over to the counter, rip off a piece of paper and drew this! Gave it to his daddy and again said "want to call Mawmaw?" (noticed this little dots are buttons) :)
