Me and My Fathers relationship

It is pretty strange relationship, We usually talk very less even when I am at home, now over the phone probably in 1-2 months and that too don't last 3-4 minutes, and if lasted more than 5 minutes than must be problem in line and we couldn't hear each other and so look so long. In my parents I am more close to my mom than my father, but sometimes it is really strange to know by someone else or by mom that though my father don't say to me but how much he do care about me, well not only from him side it is true at my side also, but I always hate to find that I never able to confess this thing in front of him ... never !
