Please answer! Could this girl like me?

So me and this girl are seniors. We are both in AVID and took class pictures. For the funny one she stood behind me and put her hands on my shoulders for the picture. she was standing on higher ground than me and was a little to the side so she kind of leaned in. Do friends do this or could she like me? we also call each other hubby and wifey. This girl is very mature and doesnt open up easily. she has never been in a relationship. her best friend told me she just saw me as a good friend however. So could she like me or is the hubby thing just playful?
