Do boys think its ok to spit game to you wen ur with your mom?

im 14 and i was with my mom at tha mall...i was in tha back of a store and my mom was in tha front of the store..so this boy cept following me around getting reaalllllll close to me..so he looked good and i wouldve talked with him if my mom wasnt around so i started to walk up to my mom and i thought he might have common sence to know that THAT was my mom but no..im standing right next to my mom and he asks me for my name and my number and says all this stuff..what am i supposed to do wen my mom is next to me? so i jus ignored him and my mom was looking at him up and down witha dirty face on.....and he cept talking to me and kept at it....do all boys REALLY think that is ok?
