I went to the pool a few times , once teaching one of my friends how to swim ( or really just how to float . ) I took some walks on the beach , alone and with company . One night did putt - putt golf and go - carts with one friend , and one day I went up to Fort Macon ( which was n't far from where we were staying ) on my bike , by myself .

Question: What may be the reason why they are explaining what activities they did ?
Someone asked them how their summer was .
