He always smiles and waves. Guys what does it mean?

Ok so I feel really stupid and overreacting for this but there's this really cute guy that works at the marina where I park my boat and I use it about every 1-2 weeks (maybe 2-3 times) year round and he always smiles and waves or in the coner of eye I'll see me watching me I just want to know what it means but it most likely is nothing but him being friendly but I'm just really curious about it
