This exactly. The best thing about bouldering is you can go and do it when you like without needing a partner. Chat to the indigenous population. I usually try an "alright mate" or give a sly nod and then work up to a proper sentence. If it's a hot girl I pretend to be interested in technique and work up to post bouldering Phad Thai.
