I think that depends on several factors.... to some it does appear to be a lot, but what if the friend was genuinely concerned that the OP was hurt or MIA? Is the OP someone who normally answers their phone or returns voicemails? With technology being how it is today its easier to reach out to check on people. I mean we don't know the state of the OP and the friend at the time they parted ways and this was over 1 1/2 days. Did the friend know the OP suffered migraines? Maybe the friend was worried? 3 days of hanging out and then nothing? My friends and I all minimally text to say we made it home, as we are concerned for each others well being and safety. Not everyone who reaches out to others should be labelled needy and or dependent. Part of friendship involves taking turns with those roles as support for each other. Too write off anyone who appears to be stepping over a boundary when one hasn't been established , is to set ourselves up for missing out on some truly genuine, caring people in our lives. This behavior is not always from a self serving place and past experience with other people may prevent one from seeing that.
