he will give you signs like he might pick you up and scare you. he might hug you or trie to kiss you. hewill get your number some how and call you. that's all the things the boy in fourth grade did to me. and I'm going to be in fifth grade this year. hope this advise helps ya'll. from the Mega Super Pretenn Relasionship Adviser. thank you :]
